I did get to thinking just a moment ago. Maybe we are just seeing a giant overhaul because there are a lot of incoming players to fit into the systems the coaching staff wants to solidify.
Obviously this doesn't hit on all of the transfers, but could explain the mass Exodus.
"We love having you, but we are really looking to give our systems a real chance this year, so you might want to look elsewhere for more playing time."
Morris and crew didn't have much opportunity to recruit and we're scouting from behind last year. Now that they have the chance, they could just be looking to bring "their guys" in. Which could be good or bad, especially on the defensive side of the ball. (Not that it can get much worse than last season)
