I wouldn't mind seeing him come back if the mandate for next year remains playoffs or bust. He's a high character guy, pretty good defender, and he bailed the Raptors out of plenty of games last season. Ideally he's not going to be putting up the number of shots he did last year on a good team, but I think part of that was born out of how bad the rest of the second unit was for most of last season. If the rest of the bench is shored up this offseason then I think he could provide decent depth on the wing.
I know everyone gets up in arms that he "stole" minutes away from Ross, but a lot of that blame should be pointed at Ross too. He made it pretty easy by stinking the place out for two straight months during the back half of the season.
