Charlie Weis is coming back for his third season as Kansas University’s football coach, but his offense isn’t.

That’s why news that John Reagan will join KU as offensive coordinator/O-line coach is a win-win for a football program that can’t keep firing its head coach every two years and can’t expect to become competitive in the Big 12 running an offense ill-suited for the college game.

One criticism of Weis you never have read here was the one so often aimed in his direction: He’s an arrogant know-it-all.

No, he’s not. He’s an obnoxious Jersey wise-donkey, but he’s not as stubborn as a mule. Never has Weis shown that he doesn’t claim to know it all more clearly than now, by going outside the program to bring in a guy who has shown he knows college X’s and O’s and wins games even when he doesn’t have the fastest Jimmies and Joes.

Weis couldn’t beat Reagan, so he enticed him to join him, not the move of a man too proud to acknowledge he is not the master of the football universe.

Reagan’s plate will be full, handling both OC and O-line duties, but maybe he’ll be able to bring one of his former KU linemen who has been working under him at Rice with him to help out. Adrian Mayes and Ryan Cantrell both are on the Rice staff.

What happens to Tim Grunhard? He’ll resign from KU.

Word began to spread throughout high school football circles in recent weeks that Aquinas High in Overland Park, which has a football head coaching vacancy, would be interested in talking to him. It’s not known whether Grunhard, former head coach at Miege, will pursue the opening.

Next season, Weis’ two most influential assistants will be former Mark Mangino aides, with Reagan running the offense and Clint Bowen the defense. Weis has proven he knows how to motivate players to bring the energy on Saturday and get it done in the classroom. Winning in football is a tough challenge at Kansas.

Heading into next season, Weis will have two years’ worth of trial and error on which to bank, and two assistants who won three bowl games in a four-year span.
