I think Kerby and Sydney are back. Kerby is having a breakout year this year and I think he sees next year as his chance. Sydney has his brother and I think he also sees next year as a year of further improvement.
Quan no idea.
Tolson, maybe its his dad's post on Rivals his freshman year when he wasn't playing, but I would guess that Hart and Barnes are penciled in as starters next year, and Tolson has no interest in being third in a two man race. I hope i am wrong because he is a good football player and would hate to lose him.
