I think you are right on as far as what his role is, and he is an upgrade over Finely, who was basically shot when we got him. However, since we lost TA there is a need for a guy to step up to backup the SG and SF spots. Obviously we have Quis but he was not good for most of last seaosn and was hurt for a lot of it as well.
Maybe Bradley can step in for some of those minutes, but he can't really at the SF spot. That's where everything becomes more uncertain. We still need to shore up the backup SF position with another player. Until we do, Wafer is not in the Finley role quite because more will be asked for him.
If we get a solid backup SF, then I think everyone will feel much better and more certain of the situation.
