As soon as Batum is ready to go again, he needs to be inserted into the starting lineup and Matthews needs to come off the bench. Matthews has been way too inconsistent. When he's awful, he's AWFUL!
I'm willing to try anything that helps us win, but don't fool yourself. Batum has been just as inconsistent.
I like your idea and have been saying all year that I'd like to see him play guard. It may ultimately be his best position. I don't like the way he is used by the coach. He seems to get pretty much the same kind of minutes he got as a rookie. Starting him at SG puts our best 5 players on the floor.
