Fes takes a lot of grief, but if I were the jazz I would try to sign him cheap and long term. On my 20 year anniversay my wife bought me Jazz tickets to go see the New Orleans game in the ESA. Fes was amazing good and bad. It was one of the few game Fes started and played more than 20 minutes. Fes completely dominated the game. He did not have amazing stats, but he controlled the middle and completely shut down the middle drive. Now he also made some of the most bone-headed plays you've ever seen. He actually passed the ball to Korver while he was standing out-of-bounds. He threw several passes to the ref and not to Jazz players, but there was a remarkable difference on defense when he in the game.
I'll go one further, we don't win the Denver series without Fes. Did he do anything amazing, Yes he did! He made nene a complete non-factor. It was not the blocks, it was his mere 7 foot 1 inch 300 pound presense. Nene would take it in inside and throw it out to the perimeter. Fes owned Nene. In the words of Melo "Fesenko, Fesenko!"
Fes was completely out matched in the Lakers series as skilled big men still give him lots of trouble. However, I for one hope he is quickly signed.
