It really depends on what we do in the draft and what other teams end up offering Tim Thomas. If we can get a backup PG and/or SG in the draft, then I could see the Suns giving all or almost all of the MLE to TT. If someone offers TT $7+ mil to go somewhere else then he might be gone (although he's said winning is more important than the money....I'll believe it when I see it). If TT is gone, we'll still have James Jones, Grant and either Diaw or KT coming off the bench at the F/C positions.
There's also a chance we draft a PF/C (replacing TT) and then need to use the MLE to go after a backup PG or SG (if they really think Barbosa can handle PG duties, which I don't think he can). The list of available free agents that was posted in another thread really didn't look too promising for the guys that can probably be had with the MLE.
