I would not be surprised if the 13th scholarship is filled over the summer by a late qualifier. Sometimes there is an opportunity to pick up a quality player by being willing to wait. Lucky Jones' recruitment having been a good example. With that said, the alternative would be to give the scholarship to Conrad. It seems he has earned it, and it would indicate a good quality about the program to reward him for his senior year. I cannot think of any reason why Coach Toole would not fill the open scholarship.
The press release mentions 4 of the possible 6 returning scholarship players. I assume Aaron and Jordan will also be back?
