McDowell, it seems, transferred to maximize his earning capabilities for what is certainly the final year he will play football.
Edwards, it seems, is transferring to help prove himself through production, proper position opportunity, elevated competition (perhaps), and film. If and when he goes and plays a true edge in a four-man front, produces, and then gets a chance to work out for pro scouts, he runs well enough and has the length that pro scouts want that I believe he'll at least get a shot.
