Urban Meyers talent will be gone by then and this current coach will probably be fired be then.
By "then" you're talking about max 6 years from now, but somewhere in between 3-6 years.
History tells us a guy without head coaching experience taking over for a legend usually doesn’t live up to program expectations
How about in the 3-6 years immediately following though?
Frank Solich was doing great in his first three years, got fired after year six but got a conference championship, three top ten finishes and a national championship appearance in there.
Mark Helfrich's first three years were pretty impressive, going 11-2 with a top 10 finish, making it to the national championship game, then finishing #19 with an injury depleted roster.
Jimbo Fisher? Followed Bobby Bowden, won 10, 9, 12, 14, 13, 10 games in his first six seasons with some conference championships, a national championship, etc.
Lincoln Riley has only went 12-2 and made the playoffs his first two years.
Remember Tom Osborne was a first time head coaching taking over for a legend.
So was Chip Kelly (10-3, 12-1, 12-2, 12-1) when he took over at Oregon, and while Mike Belotti wasn't
exactly a legend on the national stage, he got Oregon to the highest point they'd ever been.
Bret Bielema was a first time head coach taking over for Barry Alvarez. Did pretty well for himself.
