Gnarl, you almost mirror my mind!
I would definitely keep Evans first thing! You can always trade him later, if we find a big who'll play as big, and he becomes superfluous, though I don't see it happening.
I would encourage Sonny to work further in the summer and re-sign him if he's shown progress.
Keep BC, but maybe upgrade Triano. In the words of an obligatory Ricky Lake guest: What makes you think that JT won't do what he did to Bosh
and then Bargnani, to our new stars i.e. DD or ED? e.i. Not holding them accountable, thus sending a confusing message to the team. And it doesn't seem as if Triano can pump the players up, to carry on the energy for longer stretches. He's very supportive though, maybe he can switch back to being an assistant.
