I agree with you on this. If Sano can't handle 3B, well then they will move him some place else. There seem to be some mixed scouting reports on this, but most of the reports that I've seen in the past few years seem to lean more towards Sano being able to stick at 3B. We'll have to see what the TJ surgery does, but other position players that have had it didn't really seem to have a problem throwing. To be honest, Sano could probably be a little worse than Plouffe on defense and it would still be worth keeping Sano there. I like Plouffe, but let's be realistic here, it's not like we'd be giving up gold glove defense for someone with Miguel Cabrera type 3B defense. We're talking about average defense vs probably slightly below average defense. Plouffe could have a ton of trade value this year around July. There are teams looking for even an average 3B, and the fact that he still has 3 years of team control makes him even more valuable. Once again, we really only need to worry about this if everything goes right.
