The Kenny Williams Effect Posted Nov 23, 2016 The Tar Heels have been significantly more effective on both ends during Kenny Williams’ minutes at the 2-guard. UNC scores about 14 more points per 100 possessions in those minutes and also allows about 22 points / 100 fewer. Diving into the “4 Factors” numbers, it can be concluded that Carolina is much better at forcing turnovers with Williams on the court. (The Secondary Break)
