Why to the bolded? Jimbo Fisher was 45 when he was announced head coach at Florida State. He had zero head coaching experience. In year four, he wins a NC. Bob Stoops was 39 when he was announced head coach at OU. He had zero head coaching experience. In year two, he wins a NC. Dabo Swinney was 39 when he was announced head coach at Clemson. He had zero head coaching experience. In year nine, he wins a NC.
Exactly how and why isn't Frost ready? If you look at Tom Herman and Scott Frost's resumes, they're pretty comparable. Herman took over a rated Houston team while Frost took over a team that didn't win a game. Herman was at Houston for two years. Frost will have been at UCF for two years. Obviously, Texas thinks Herman is ready. I fail to see why anyone would question whether Frost is ready.
