The only part of this that's true is Deron has more power. No way Deron has more stamina. I never even saw Stockton sweat let alone look tired. Speed and Footwork are about equal. Deron is probably a better dribbler but then again Stock simply didn't get fancy so who knows?
Dwill on average plays about 5 mins more per game than stock averaged. So maybe this lends some evidence to the "stamina" argument?
