Last thing we need is yet another high-usage, score-first (s)wing.
Why? We certainly need an offensive wing off the bench.
Cause he'd be taking shots away from the Jays and he's clearly worse than the Jays. Both Tatum and Brown have score-first mentality. If we are going after a (s)wing, gimme a player who can contribute to winning without demanding the ball in his hands. Ideally, someone with above average court vision cause we lack a headed playmaker in the half court. For instance, Kyle Anderson, Nic Batum, healthy Joe Ingles, etc.
If we can somehow acquire a better player than Brown (for instance, Beal), then Brown would have to adjust in a more limited role. Unlike Kuz, Brown is a 2-way player, hence he doesn't have to score loads of points to impact winning. I reckon he'd be an elite 3rd banana.
