As long as the Jazz are perennial contenders and doing everything they can to get to the Finals each year, I think he'd stay.
Players like Lebron, Wade and Dwight are now showing that it's about winning championships, not about playing in New York or LA.
The Jazz are in a good position to keep an elite player at the wing if Favors, Burke and Hayward pan out to give that player a strong supporting cast. In other words, they're building in the right sequence.
The Jazz are doing the right thing to lay the foundation of a good team with the young players we have now, so when a big star comes in, he's not alone.
