As a South Florida native and frequent attendee of Canes games (wife is a UM grad), the scheme has been the problem for Van Dyke. Gattis has been heavily criticized for trying to fit round pegs into square holes, but when he's let Van Dyke cook, he looked very good before getting injured against Duke (350 yards with 63% completion rate against VT, nearly 500 yards and 75% completion rate against UNC).
He was excellent playing in Lashlee's RPO system before the latter left for SMU, and I think he's a perfect fit for running the offense Tommy and MFMF want to run. I'd be thrilled if he transfers in to ND next season, as he'd have a lot to prove and would be an immediate improvement over everyone currently in the QB room.
