Rhule's an above average coach. His specialty is finding guys with the right measurables and developing them by coaching fundamentals. He looks for length, speed, and absence of arrests. He likes the three star guys that are happy just to get an offer, cause he knows they will put forth maximum effort to prove something.
He wins the games he should win. You never had those "what the fuck?" games like I got so frustrated with the Longhorns about ever since Mack retired while on the job, where they'd have a team they should slaughter, and then go out looking like they've got a Pepsi bottle stuck between their butt cheeks.
His quarterback management, both at Baylor and Carolina, is goofy. IMHO, QB management killed him at Carolina. At Baylor, he lucked out with Charlie Brewer, but ran off Zach Smith, a four star out of Grandview, for transfer Anu Solomon, who was also a four star, but tore up his shoulder in Arizona, and didn't have enough arm strength left to pop a balloon with a dart.
His recruiting is pretty bad, in terms of getting the top rated guys, and he's stuck in the JoePa mythos. Not the Jerry Sandusky stuff, but the plain uniforms, lunch bucket, blue collar attitude. Not sure how he'll fare in the NIL era, but his recruiting classes would be in the 30-40 ranking if he was at Ohio State or Bowling Green.
TL;DR Good coach, not elite, can take you to a top 20, probably not to the promised land.
