I think he should come off the bench as well, but Baynes should start once he is back, not Smart.
That said, Gordon is like a son to Brad, I don't see it happening. Nor do I think we can make this sort of conclusion after 5 games especially when the guy has hardly played basketball in over a year.
He does look lost out there though, just hanging around the baseline, not really moving without the ball and not really getting any passes to shoot.
I also think it's a bad look for a max guy to come off the bench, in theory who cares? We the fans don't, but other potential max guys that want to play here might..
