Brooks' take: "It's a battle of the running backs, looking at Melvin Gordon and how he plays against a pretty solid defense. Ameer Abdullah, how does he look coming off injury? Scouts always wonder how someone plays when they are less than 100 percent. For Nebraska DE Randy Gregory, how does he play against the run? Wisconsin will test him with a pro-style, zone-blocking system. How will he fare when they run right at him?"
