Trevor Berbick Carl Williams Tim Witherspoon Mike Weaver Marvis Frazier ( the version that beat Smith)
He'd outbox all of them, KOs Frazier He could be caught by Witherspoon and KOed but I think he makes the distance and takes points win. Berbick causes him some issues, but he adjusts and takes another decision Tbh this would be a hard task for Ezzard but he could definitely do it
