Yeah, you slot Bradley in at point and let him move off the ball and knock down threes (39% last year? something like that) and Demar takes the ball up the court like he did a lot of last year. You'd need a lot more movement and less isolations with that kind of offense but I think I'd enjoy that, honestly. You wouldn't lose a thing on defense Lowry->Bradley. I think Bradley might even be better.
Isaiah's defense.. from what I've heard, from a guy his size, it's good, but next to league average, he's some below average. You can cover him without worry though, he's not THAT much of a liability. And market price on him is like 6-7m.
Imo Isaiah > Collison but there's always the trade route. Wonder who's out there.
