Here’s what I don’t get. Most of you love Jim Harbaugh, the coach. You keep telling me that and you keep telling me not to harp on his social inadequacies — no one cares about the media yadda yadda, etc. You tell me he wins and that’s all that matters and he’s a great coach. OK, so this great coach just made an unprecedented QB change. Now a bunch of you are defending Alex Smith and treating Harbaugh like he violated a saint. Well, you can’t have it both ways. If Harbaugh is so great you must trust he knows what he’s doing. Maybe this QB shuffle — so unexpected, etc. — is part of his greatness.
