If someone captured Sully and whipped him into real shape, I mean solid condition... like a real 245-248 lb. or so, you could see him being an all-star, averaging 18 to 20 ppg 10 reb. and 4 assists. He's developing a go to guy attitude. His speed, quickness, and stamina would really improve.
But alas Sully will not be captured.
Next choice is James Young, but way too early to even think about it.
