Well the thing is TJ will be playing really soon, and if we do a decent run in the playoffs, his value will rise again, he is an ambicious player and I bet he will be playing pretty well when his back.
Another thing is TJ being best friends with Bosh, that is important, but I have noticed that Bosh
chemistry is also pretty good. They always sit together in the bench and are always talking to each other. Also Calde is much more social (not saying TJ is a worst person, he is just more introverted), and has the european flavor this team likes, sharing same 1st lenguage with two other important players in the team.
I see Calde staying, with Ukic next year as a backup, TJs value rising again before the end of this season, and a trade involving him and maybe kapono in the summer.
