Bertans The Idea is way way wayyyyyyy more useful than Bertans The Player. Yes he can make long shots, but he can also miss them in bunches. He's like a box of chocolates, as they say ....
He has no reliable way to help, other than if it happens to be the night where he might make a shot or two. It's hard to find a place to play him. The Mavs weren't the 1st team to give him a try and then figure it out and move on, and it's still the same story -- OKC last season, badly needing shooters, barely used him and eventually sent him away. Even if he's available at the minimum, I think the Mavs can do better.
