IMO, here are the twelve guys with the best chance to break camp with Atlanta's staff:

1. John Smoltz - #1 starter.  If he puts up 200 innings again this year, they should put up another statue for him outside Turner Field.  
2. Tim Hudson - #2 starter.  Watch Hudson surprise everyone with an all star season this summer.
3. Tom Glavine - #3 starter.  This move drips with nostalgia, but I look for Tommy to fade badly after the all star break.  All the warning signs are out there.  I think this is a one-season retirement party, with a run of quality starts prior to the all star break.
4. Mike Hampton - #4 starter.  I think he holds up in ST and initially receives kudos for his hard work and resilience.  Then, I think it will take him 5-6 starts in April and May to get his command back.  We will see if he can stay healthy throughout 2008, but that's simply a crap shoot at this point.  I'm guessing he will have a somewhat better season than most people expect, but perhaps after a slow start.
5. Chuck James - #5 starter.  Here is another spot where all the warning signs are out there.  He is only 26 years old, but he had to go on the DL on August 21 with a "tired arm".   Now his shoulder hurts.  That's a problem.  He is a two-pitch pitcher who has not worked hard enough to develop a third pitch or to study the tendencies of NL hitters.  Most young pitchers with this kind of persistent shoulder pain turn out to have significant injuries, and we already know he has a rotator cuff tear.  They said it was "small", but we will see.  He may break camp as the Braves' #5 starter.  Or he may be traded in March.  Or he may break down and go on the DL.  We will see.
6. Rafael Soriano - Closer.  He has never been a closer before.  From Mid-June to mid-August, he had gave up nine HRs in 24 innings.  Then he made adjustments and allowed only one run in his last 17 innings of 2007.  Which Soriano will show up in 2008?  I'm guessing he will always give up an occasional untimely HR because he challenges hitters with heat.  But I have no doubt he will be the best closer the Braves have had since John Smoltz went back to the starting rotation.  
7. Peter Moylan - Setup.  Everyone expects Moylan to regress in 2008.  To be fair, I don't expect any pitcher to sustain a 1.80 ERA every year.  The thing that made Moylan's 2007 season so effective was his .242 BA allowed against lefty hitters.  It is very unusual for a righthanded sidearm pitcher to pitch that effectively against lefty hitters.  I don't know if Moylan can do that every year, but he is a big, strong pitcher in the prime of his career at 29 years old.  He throws harder than most sidearm pitchers, and he had great command in 2007.  that's why he was able to post such a great season.  His motion is not the kind that fatigues an arm, and I think he will pitch effectively again in 2008 as the setup man for Soriano.
8.  Jeff Bennett - I think he breaks camp as the long reliever, or possibly as the fifth starter if James is hurt or traded.  I think he will have a solid season in Atlanta in a variety of roles.
9. Tyler Yates - Electric stuff, with a killer slider when he is able to spot it properly.  But his command has always been his weakness.  He will make the staff again, because BC likes him as a situational reliever against righty hitters.
10.  Blaine Boyer - Blaine is out of options.  He is healthy again for the first time since 2005.  The Braves haven't forgotten what he accomplished in 2005.  He pitched well, with good velocity, in Richmond for the last 6 weeks of 2007.  I don't think the Braves will let him get away.  He will start the season in Atlanta, and be given a shot to show what he can do.
11. Will Ohman - He is an effective situational lefty reliever everywhere except Wrigley Field.   He doesn't have great stuff, but he is a veteran who knows NL hitters.
12.  Royce Ring - He is out of options.  He throws hard, and he showed some signs in 2007 of developing better command.  I think he will break camp with the Braves by beating out Jeff Ridgway in March.  If Mike Gonzalez makes it back in 2008, Ring will have to beat out Ohman to stick in Atlanta.  Otherwise, he will be dealt in mid-season.

Manny Acosta - This is the guy who made it easier for Frank Wren to trade Joey Devine.  Acosta has the best stuff of any righthanded Braves reliever except Rafael Soriano.  He pitched well against righthanded hitters in Atlanta in 2007, but he still walks too many batters.  Once he develops better command, he will be a very effective major league set-up man.  He has an option left, and I think that may cost him a major league roster spot in April.  Unless he can beat out Tyler Yates, I suspect Acosta will narrowly miss making the Braves' pen in March, then we will see him come back up as the first reliever recalled from AAA.   He may even be a future closer candidate.

Phil Stockman - He has electric stuff.  If he stays healthy, we will see him in Atlanta in 2008.  He could turn out to be this year's version of Peter Moylan.

Zach Schreiber - This is the year he makes it to Atlanta, but not before Acosta and Stockman.

Chris Resop - Like gondeee says, he has a shot in March because he throws hard.  But this staff already has one hard throwing situational reliever with poor command (Yates), and I don't think they will break camp with two.  And if they do, IMO the second one will be Acosta, not Resop.  But if there are injuries or blow-ups in march, Resop has a chance.  Otherwise, I think he gets cut.  He could end up waiting his turn in AAA, or he could get claimed by another team.

Charlie Morton - He throws hard, he pitched very well in Arizona in the fall, and he has an option left.  If he pitches well in AAA, he has a chance to make it to Atlanta sometime in 2008, perhaps even ahead of Jair Jurrjens.

Jair Jurrjens - He has an option left.  If Chuck James is hurt or traded, he will get a long look in March.  Otherwise, I think he begins the season in AAA.

Jairo Cuevas - 6'2" 24 year old righty has great stuff but no command.  At Myrtle in 2007 (6-12), he pitched 132 innings, surrendering only 113, with 71 BBs and 116 KOs.  This is Manny Acosta all over again.  He will be moved to the minor league camp by mid-March, but he may be a name to remember for 2009.

Buddy Carlyle - His 2007 performance was gutsy, and may have saved th Braves from a serious folderoo.  But his stuff is AAAA.  Barring a catastrophy involving multiple injuries to starters, he cannot make the Braves staff in 2008.  However, the Braves would like him to pitch well in March so they can trade him for an A-level minor league player with upside.

Jo Jo Reyes - He has an option left, and he will start the season in AAA unless he beats out (or replaces) Chuck James.  Reyes is a lefty starter with electric stuff, but his command is in the early stages of development.  Thus, he typically falls behind in the count, makes too many fat pitches, and walks too many batters.  Still, I think this is the year Jo Jo develops into an effective major league pitcher.  Keep in mind, also, that Jo Jo will become very conspicuous trade bait if Frank Wren goes after a big name.

Mike Gonzalez - he is due back from rehab after the all star break.  He is said to be ahead of schedule.  I believe the effectiveness of his return will have a lot to do with whether the Braves are contenders down the stretch.

Jeff Ridgway- Was acquired as insurance, in case Gonzalez doesn't make it back.  I do not think he can beat out Will Ohman and Royce Ring in March.  Ring is out of options.  Ridgway still has an option, and he will start the season in AAA.  

I think a little background on Drese is necessary here. He had a good year in 2004, winning 14 games for the Rangers, keeping the ball on the ground like a solid back-of-the-rotation starter. Sure his K rate was low, but as a back-end guy with a good sinker, you can get by on 4.5 to 5 K's per nine.

Then he started having problems. Though he was still keeping the ball on the ground, his K rate dropped from danger zone to intolerable. At this point, all hell broke loose. In August, he started complaining of soreness in his right shoulder that wound up being a labrum tear which required surgery in September. He had surgery and made it back in April of 2006, but then went immediately back on the DL (leaving the game during the fifth inning in his second start). Diagnosed with a partial tear of his UCL, he tried rehabbing but never made it back. He then had Tommy John surgery.

I'm not saying that the drop in his K rate was definitely due to arm problems, but is it possible that he was never really 100% in 2005? Is it possible that his labrum was bothering him a little all year? It's not uncommon for fringe-type pitchers to conceal injuries (just ask Anthony Lerew or Chuck James). Now, he's finally gotten all the crazy surgery stuff done. I think he could make it back, not as a star by any means, but at least as a decent sinkerballer in the #5 slot.

Jayson Stark agrees with me:
"Nobody accumulates potentially useful pitching options like the Braves. They quietly signed one-time 14-game winner Ryan Drese late last summer, content to let him ease back from Tommy John surgery. Now they're bringing him to camp with an eye toward stashing him at Richmond until they need him."

Why does everybody keep hating on this guy?  Granted, I wouldn't say he's going to make the team out of camp, but neither are Charlie Morton or Buddy Carlyle, and they got "even" arrows.
