I agree that I like Quentin more all things being equal. The DBacks just have a LOT of money tied up in their corner OF and barring a trade (of Quentin), I think he'll be stuck next year - sort of like Lane last year (with the proviso that Quentin is a MUCH better prospect). Obviously, injuries can happen and maybe the DBacks will come to their senses with Green, but if they can pull off the improbable and contend this year, I can't see them shipping either Green or Gonzo out. Who knows for sure.
Anyway, as for making the decision tougher, just remember there are no guarantees. That's why I like this game - kind of like the stock market and we're just gambling on future performance. Of the two, I like Quentin more personally. But, based on your desire to have a starter in 2006, Hermida would be my choice. However, he could suck it up big-time in ST and be at AAA next year as well, while Quentin plays so well he forces the DBacks to move Green to 1B and trade Tracy.
Lastly, I'm originally from Atlanta, but moved to Orlando at a young age. Lived in different places in Florida - currently live near Tampa. More a baseball fan than a Rays fan, but as they are the local team, I support them and go to a few games when I can. Braves are the other team I root for, but they seem to have greater representation here. That explains the avatar. I'd personally rather have an avatar (and signature) of Kate Beckinsale, but not sure the g/f would appreciate that.
