You win in the playoffs with veteran ballplayers. TT was a veteran that seems to play better in the playoffs. He is up and down during the year and the suns know that and D'Antoni even talked about it.
You can not win a championship without good players off the bench. (Miami heat!)
If Amare comes back healthy it will make a large difference how the suns do in the playoffs next year, but how about those games where Amare and KT pick up a couple fouls in the first quarter and you need to go to the bench. Or, someone gets injured!! That is when a guy like TT is really valuable. It is extremly hard to find a 6' 10" player with his skills that can play 20 minutes and do what he does. He is not afraid of anybody on the opposing team, and wants to take (and makes) the big shot if needed, and even though he does not always play great defense, he played some very good defense in the playoffs when needed. The part of TT that I will really miss other than his offense, is the way he protected Nash a few times with hard fouls and even a shove to another player just to let them know to leave him alone. I have not seen anyone of the suns do that for years, including Amare, and now TT will not be there for that toughness that he gave us in the later part of the season and the playoffs.
Do not underestimate TT when it comes to winning big games, I think the Suns just did.
