Will is a quality coach and an even better person, and we want to thank him for his contributions to the Redblacks organization over the past two seasons. We wish him all the best.”
The Redblacks announced that Jeff Reinebold will assume the defensive coordinator position and Nate Taylor will take over as special teams coordinator.
