Rhule isn't a criminal guy. Briles was, but I covered Rhule his first year, and he kicked a bunch of guys off the team. I also used to check arrest reports monthly, and it wasn't a problem. Briles? Yeah, I broke a couple of stories on his players getting arrested.
Rhule recruits measurables. He runs a bread and butter offense and defense. He's one of the best at getting the most out of his talent. Jalen Pitre was a three star, and got picked #1 in the second round of the draft. His players come out of the college game with full preparation for the NFL. Nice guy in front of the camera, tyrant behind it. One of the reasons he had problems at Jacksonville was the pros didn't like his military type attitude.
Remains to be seen how he'll fare in the era of NIL and transfer portal, but make no mistake, he encouraged a lot of people to, in his words, "be successful somewhere else."
Agree with you that Nebraska will probably suck in year 1. That's Rhule's MO. He establishes his system, and come hell or high water, that's what's going to happen. First year at Temple sucked. First year at Baylor sucked.
