Looks like you nailed most of it. Don't feel so bad about Sura, he had a good run, but just does not have the wheels left to contribute. A nice guy, though, and a heck of a competitor. Bowen and Azbuike really do look like guys without a place on the bench, but I am not sure how management will look at the last spot on the roster and the three extras. TRADING TWO OF OURS FOR ONE OF SOMEONE ELSE'S WOULD BE GREAT! However, it is hard to find basketball fits that fit the cap and TR limits.
Haryasz might be the man to go, but you can't teach height.
Lucas is a definite possibility, but may get an extra spot.
Jameson is a possibility to be cut or get an extra spot.
Padgett could land anywhere from the roster to the garbage heap.
Novak is likely to get the 12th spot, but could get the 3rd extra spot.
They definitely need someone in the middle in addition to Yao and Dek, but is Haryasz that man?
Yao, Dek, Howard, Hayes, Battier, TMac, Snyder, Bonzi, Rafer, VSpan, and Head look like making the roster without a trade. Personally, trading Head and Padgett, Lucas, or Haryasz for a better backup PF/C would allow them to carry a shooter like Novak, Jameson, or Padgett without worrying about any injury at Center. This is a good lineup in an imperfect world.
