The 6-foot-4, 170-pound shooting guard was looking for a place that he could help impact right away, and after a visit to Northwestern, Cobb decided that was the place for him.
"The opportunity that i would have there stood out," Cobb said. "It's in the Big Ten. I got to play with the guys and I think I can help them right away."
"I think it was the opportunity to come in right away and impact, plus it was the education," he added.
Northwestern assistant Tavaras Hardy was the point man on Cobb's recruitment, and according to the three-star prospect he played major role in his final decision.
"We got to know each other real well," he said. "I just felt like I could trust him."
Cobb is Northwestern's first commitment for the 2010 class.
