We've debated in other threads where he'll head next. I'm really curious to see his next move. After getting tired of his act as a writer, I've come to enjoy him as an NBA analyst/show host.
My thought now is that he goes the Dan Patrick route where he does deals with a bunch of different networks/sites. Writes once a month for SI, hosts his own podcast, hosts a show on NBATV, appears on TNT, does a production deal with Netflix, etc.
Edit: Good point on Grantland, jnai. If they can find a good editor in chief, maybe nothing changes there.
Second edit: Lots of Twitter speculation that he could go to Yahoo. That would surprise me. Yahoo's future is a little too cloudy for me to think they're a smart play unless they overpay him significantly.
