Whatever is causing it to work, it seems like a great core is in place and unless they get something amazing in return (Anthony Davis like) I will be very disappointed if they mess with it. I am not at all worried that they will, BTW.
One thing I love about Favors is his team orientation. He believes something special is happening here, and his words and actions are going a long way toward making that into a reality. Additionally (somewhat related), the way he dealt with his last contract is a mega-positive in my book. His attitude is worth a ton!
