Alex Gonzalez is probably the most divisive player on our roster -- really because of the way he was acquired rather than anything he's done. If we can drop old news, I think the discussion of Diory Hernandez vs Gonzalez is one worth having.
I know that this is in the realm of fantasy, and that unless Alex is injured Diory will either be warming the bench in Gwinnett. However, I think there is something to the idea that Diory could actually be the better overall player.
Gonzalez is a known quantity these days -- Bill James, Marcel, and FanGraphs fans all project him as pretty much the same hitter. Marcel's "optimistic" projection sees him as good for a .303 wOBA. Gonzalez is a major leaguer because of his glove alone, and would be the first choice on our squad should the "Designated Fielder" rule be created.
The Fans see him as a +5 defender at short, which seems fair to me. He's historically been a +5 and over defender, but with another year on his body, 5 seems like a good number. Paired with around a .300ish wOBA, that would make Gonzalez somewhere in the 2 WAR range.
Hernandez, on the other hand, has turned in a pair of nice AAA seasons the last two years. His ABs have been limited, having spent a fair share of his time chewing sunflower seeds on the big league club's bench. However, he turned in a .336 wOBA last year and .369 the year before that. He'll be 27 this season and could be entering his prime.
Though I'm not an expert on Diory's defense, he's played short stop as his primary position throughout his career, and was thought well enough of to be the backup defender at various points last season. I would not expect him to be at Gonzalez' level, but could perhaps be a league average short stop.
Could the potential increase in offensive production make up for the presumed drop in defensive quality? Is Gonzalez too important a piece on an infield as dicey as ours?
