Believe me, LaRoche is no comp for Napoli. He can't catch, he can't hit as well in Fenway, all he does better than Napoli is field 1B better. He's basically a #7 hitter - and don't be fooled by his 2012 season, it's an outlier.
Agreed, Laroche would be a massive blunder. Plus, we'd also lose our 2nd round pick (which is pretty high) in this years draft and the slot money that belongs to that pick.
