Until the playoffs change, it would essentially mean that Miami would have to run the table, 12-0 or 11-1, and knock of Clemson in the championship game for the ACC as far as I know. More or less similar to Oregon in the Pac-12, except they tend to play a slightly easier schedule since there are fewer conference games.
He would need to get that talent base in the program, which should be easier for him there, and then use it effectively to get that type of record. I'd say for our experience, the Rose Bowl year was as close as we got, derailed by just one game.
