I haven’t watched anything on the channel lately, but Penn State’s wrestling title is featured as one of the top stories currently on BTN’s website. Haven’t seen anything on swimming or fencing.
That said, three B1G teams also advanced to the Sweet Sixteen this weekend, and more than half of the conference was participating in the NCAA tournament. Considering the relative difference in popularity and interest between the two sports, it’s not entirely surprising that the Sweet Sixteen teams get higher billing. I think the same would be true if Ohio State or Iowa had won the wrestling team title.
