From the outside looking in, I really think Sully has been the key to strong team chemistry this year. He and Jeff get along so well (as you can see in the post game interviews).
At the same time, I think Avery, Brandon and Favarani of all people are the ones leading by example.
I can't wait for Rondo to get back. If I were Ainge, I hold back on any big trades. This team has too good of a chemistry right now. If anything, I think Humphries, Wallace, Brooks and Crawford are the ones who could be traded without much of a hit to the team chemistry.
I just really think Sullinger and Stevens are the best things that could have happened to this team. I don't trade Jared for anyone.
