Coach Auriemma did not allow Kelly Schumacher to play volleyball. It is doubtful, he would change philosophies.
It is hard to question the dedication of an athlete who chooses to play two sports; Especially when they are very, very good in both sports. Coach Hatchel certainly had no problem with her elite track star back in the 90's; And still managed to win a national championship with her track star as her point guard.
UConn has had very good track teams within the Big East, but have never been a major player nationally. Such an athlete could only enrich UConn's track program.
I can understand Ms Williams desire to pursue a basketball scholarship. I do not know the current situation with track and field. Back in the day, track and field athletes only received partial scholarships. Today, I believe, sports like track and field and swimming are highly subsidized on a number of college campuses by way of university sports clubs.
