It's a risk to renounce Hood/Exum, drop Thabo and Jerebko, let Favors and JJ walk and give up an asset to unload Burks to offer a RFA with 2 turn ACLs
It's a bigger risk actually paying Hood any kind of serious money. Favors is a poor fit, and I doubt he's interested in staying with the Jazz anyway. The rest are role players that can be replaced with other cheap role players. Like, we're really worried about Jerebko or 37 year old JJ?
