If he leaves it will be a complete rebuild job looking at the current Fr and So classes as well as the inevitable transfer exodus.

If you are saying he elevated VT’s profile, maybe slightly. Takes more than some 10-8 ACC seasons to do that. Greenberg had several good ACC seasons. Buzz has strung together seasons unlike Greenberg but this success is all Buzz and not some seismic shift in VT profile, IMO. If we drop to the basement for many years after he leaves few will be surprised.
