The question is, why should the Cavs volunteer to pay additional tens of millions in tax just so Rich Paul can save face. Tristan's options are 1. Get Philly or Portland to offer you the max (not happening, and I doubt he would want to play for either of them); 2. Sit out the entire season, watch his market value drop, and become a RFA again next season; or 3. Sign whatever contract the Cavs offer him.
I really doubt any of the first two options are real options for Tristan. He can hold out and play games, but eventually he will have to sign whatever contract the Cavs offer him because any other option is far worse for him. If it weren't for the LBJ connection, the Cavs could've offered him a 5/45 contract at this point, which is not much less than he would be able to get on the open market, and he would have to take it because sitting out a season would drop his value even further. Thanks to LeBron, the Cavs will likely keep whatever they previously offered him on the table. He should thank his lucky stars and take that offer. No need for Gilbert to give him a reward for trying to blackmail the franchise.
