Despite playing in multiple games, Darius Wade and Jon Hilliman both received medical redshirts for last season. It is good news for everyone that they now have more playing time, however, with regards to program building, Wade is the bigger deal.
Hilliman is going to play and probably play a lot next season. Even coming off of injury, he will still be BC's best running back. The medical redshirt gives him one more season, but it doesn't impact his immediate future nor does it really change his status at BC. Maybe he will transfer as a fifth year, but more likely he will continue to play out his eligibility if he is happy.
Wade is a different story. With Towles coming in, his opportunity to start is challenged. He might have to sit for another year. If he had not received a redshirt, sitting might not make sense. It would only leave him with one more season of eligibility. No worries about immediate transfers. It would also be ideal for his health and learning the new offense. BC needs long-term stability on offense, so by having Wade develop slowly -- and happily -- BC and he can hopefully benefit in 2017 and 2018.
