Three to know: No. 9 North Carolina vs. Northwestern Posted Nov 23, 2015 Chris Collins is in his third season as Northwestern’s head coach. The Chicago-area native should be familiar to ACC hoops fans. He was a shooting guard for Duke in the mid-1990s and served on Mike Krzyzewski’s staff for more than a decade. Seven-foot senior center Alex Olah has been a major cog in the Wildcats’ attack, averaging 13 points and eight rebounds. (Fayetteville Observer)
