Who's going to QB the 49ers Sunday, Alex Smith or Troy Smith? Only Mike Singletary knows, and he isn't telling. He claims he has already made up his mind who'll play against the Rams but also says it might be both. Both QBs will get their share of reps during the week in practice.
Personally, I think Singletary's just recognizing he has a pretty classic Giant Douche vs. Turd Sandwich dilemma here, and doesn't want to admit he actually has to start either guy.
