I voted yes. I think it is 50/50 as well.
This was my logic before reading that Stein tweet about GSW and OKC being the front-runners: GSW is the easy way out...he won't do that. Clippers are cap-mathematically eliminated. Miami, outside of Whiteside, is hurting. Wade may leave (doubtful) and Bosh has those health issues and may have to retire at some point. San Antonio seemed like a maybe, but would have to do some maneuvering. Boston was a great fit. Maybe wasn't the best WIN NOW scenario, but had a very, very bright future and still some great assets to improve going forward. OKC, obviously the home-team, has a great chance.
I was on CSNNE.com last night and read that Horford going back to ATL article, so everything is speculative at this point. I still believe Boston is in the running. He probably has it narrowed down to OKC, Boston, and GSW. That's my personal belief.
