I think Bojan will get offered a 4yr deal starting at $200K less than Favors' cap number (so Jazz don't have to release Neto or Niang). Other teams can certainly offer more; Jazz aren't going to be able to outbid everyone. The pitch will be to play for a legit contender. Indiana might vie for a 5-8 seed. I guess they could catch Toronto if Kawhi leaves, but Philly, Milwaukee and Boston will all be better than Indiana, with the strong possibility Nets will be too.
If Bojan joins the Jazz, it's probably between Jazz and Denver for 1st. Portland will hang in there, but I don't think they'll be better than us. And the Lakers, even with a 3rd max FA still have a crappy bench. Of course, that may change with ring chasers joining them.
As for Portis, I guess they're meeting with him as a Plan B. Hate to release Favors, make an offer to Washington and then they match and keep him or trade him elsewhere.
