At the beginning of the season, Ivy fans were bewildered that Yale captain Kyle Mullen--widely expected to be an Ivy defensive player of the year candidate--left school. Most assumed that it was academic-related (it happens).
Apparently, he was accused of sexual assault, and opted to leave Yale before the charges were adjudicated before the student board.
Obviously, there are bigger issues at play here for all involved. And I hope that things work out for all. But strictly within the realm of football, his departure was a big reason why Yale underperformed this season. I seriously doubt he returns to Yale next season.
