Former NFL TE Kellen Winslow Jr. pleaded guilty Monday to raping an unconscious teen and sexual battery involving a 54-year-old hitchhiker.

During the plea deal, Winslow's attorney revealed that the ex-NFL star is currently suffering from CTE. Could that have impacted his behavior? SI legal analyst Michael McCann weighs in.
