I see no reason (from the 'Cats point of view) not to trade Law for some kind of power forward.
I think UPS can play PF right now, but ultimately he should be a SF. He's young and athletic enough to handle PF as a back-up this season, until we can get another one.
As a rookie, I expect nothing from Henderson. I expect nothing from Brown, either, but it's nice to see the kid can play! Hendo will be okay. Perhaps he will get a D-League stint to gain more experience.
