Well if Sheets leaves next year do we even have a playoff caliber rotation with Gallardo coming off of major knee surgery, Parra, the mediocreness of Suppan, McClung and the less than mediocreness of Bush? That's why many feel the time to go for it is now. Sheets is a free agent after this year, he likely won't be back. The young hitters are getting older, we won't be able to afford to keep all of them so what do you do if you're Melvin? Just stand pat and hope every single thing breaks right, Sheets re-signs, Gallardo returns to his awesomeness before the injury, Parra keeps improving and McClung stays with a low to mid 4's ERA? That's the type of thing that gets GM's fired. Could this trade end up coming back to bite us in the ass? Definitely. If LaPorta turns into Braun it doesn't look good that we gave up six years of him for a rental. But what if LaPorta is a bust, Sabathia leads us to the playoffs or better yet the World Series and the players we draft with our compensation picks turn out to be good major leaguers? Looks like a pretty sweet deal for us then. Hell, this deal could still look great for us even if LaPorta turns out to be a stud.
