1. I don't think Houston wants him at all. If they did, they would have just included him in the initial trade.
2. I'm not sure that Pittsburgh views him as better than Trubisky. Maybe they do, but I still don't think he ends up there.
3. Carolina I think is just going the draft route. Same situation as Houston, which is if they really wanted Baker, they'd probably already have him. Cleveland knows the price for him right now is super low.
Ultimately won't be surprised if Cleveland just keeps Baker. I think they know Watson is going to get suspended, and probably for like 4-6 games, so if they view themselves as a contender still, they'll want somebody competent in there.
