I love the versatility both bring to the floor. I think they'll be the first to understand & define their roles early on. They are vets, know their own games, and have a good feel of what they can or can't do.
People talked about Sullinger complimenting Olynyk and so on...but I think Hump compliments a guy like Sullinger pretty well and I could easily see both of them starting at the 4 & 5 positions together.
Crash can play the 2 & 3 at any point, and with anyone. I think Stevens has a tough job in putting in these players with the right combinations, but he'll eventually find what works.
I personally want to see this group play out there more together :
Bradley, Wallace, Green, Sullinger, Humphries
