What makes anybody think Anderson's going to change his routine of starting Mathis for defensive purposes and bringing Wusu off the bench to see significant minutes? He trusts these guys and Storr or anybody else is going to have to earn the ability to step in as a replacement, coupled with a significant decrease in ability from Mathis and/or Wusu.
As far as Wusu's ball handling skills: Curbello.
Going into the season the starters are probably going to be Posh, Curbello, Jones, Soriano and the 5th spot is open.
