Sorry to be disagreeable but Davis and green only grab the boards that fall in their lap. I haven’t seen either one of them get a hustle rebound all season so I don’t think your theory would work.
Davis has to outfight 3 or 4 opposing players for a rebound because Green/Niang just don't or can't.
What I'm saying is that Bradley can rebound. And he's a BIG body. With him in the game Davis would be able to roam more freely on the glass.
