For sure, but I dont think you want your best player having to become the primary wing defender when that's not his primary defensive position. It's something he can do, but I wouldnt make him start games doing that.He's actually done a decent job guarding wings this season. I see your point though, asking him to do it more often might wear him down and negatively impact his offense. Just trying to figure out a way to get Kessler in the starting lineup, and I really don't think him and Vando can be on the floor together.
Walker just has to come off the bench until a trade or injury happens. The Ivory Towers can work, but I dont think it's something you want to start with.
