I think we all know the answer to that question............no, he's not. Sabean went out a traded for him anyway. There is little chance that he is going to admit his mistake of moving Alderson for this injury-riddled quasi-bum. Sabean intimated in his press conference that if he can't get a multi-year deal done with Sanchez, he would exercise the $8M option to bring him back. Good job, Brian. Way to undercut your negotiating leverage there.
Anyway, the pont of this is not to point out the obvious stupidity of our G, but rather to pose the question: IF you're going to spend $8M on a 2nd Baseman, why wouldn't you do it with this guy?
