1. Texas Tech defensive coordinator Matt Wallerstedt resigns after allowing Arkansas to score 49 points.

The Red Raiders getting beaten so badly by Bret Bielema’s Razorbacks, 0-8 in the SEC last year, that pretty boy coach Kliff Kingsbury got rid of his coordinator? Funny, at least to SEC fans.

When ESPN and others report that Wallerstedt resigned abruptly after he “was suspected of being under the influence of an unknown substance while on campus?” Not funny any more.

Texas Tech allowed 438 rushing yards Saturday in a home loss. The Red Raiders are off this weekend. If Texas Tech wanted to go in a different direction, it makes sense that the team would’ve fired Wallerstedt on Monday, maximizing the time at the wheel for now-promoted linebackers coach Mike Smith.

We don’t know what substance Wallerstedt abused, assuming the report is true, but no matter how bad things get, you can’t show up to work under the influence. I don’t know Wallerstedt or his situation, but it’s nothing for opposing fans to gloat about.

2. Jameis Winston is newest college football bad boy. Is he badder than Johnny Manziel?

A sexual assault accusation that never led to a trial, some minor legal incidents for destruction of property and carrying a pellet gun, sealing crab legs, and now yelling sexual obscenities in public.

All that, and Winston has to miss the first half against Clemson. It’s the same punishment Johnny Football faced against Rice in the 2013 season opener, though comparing Manziel’s offenses to those of Winston is apples to oranges.

Winston’s draft stock, as judged by national analysts, finally is bruised, if not suffering — but as long as FSU can at least stay even with Clemson in the first half, the Seminoles should stay on track to defend their national title.

3. Texas QB David Ash retires.

Ash has struggled with post-concussion issues since suffering a few significant hits early in the 2013 season. Charlie Strong said there was “no way” the training staff could’ve allowed Ash to continue to play, but that the quarterback made the decision to step away from football on his own.

Meanwhile, touted sophomore Tyrone Swoopes has averaged a paltry 5.1 yards per attempt during his still-young college career.

It’s a sad story for Ash, but it also exemplifies what ended the long career of coach Mack Brown at Texas — the failure to recruit and develop elite quarterbacks in the last five or so years of his career. Forget all the noise — if Strong wants to succeed with the Longhorns, he needs to identify a Teddy Bridgewater type signal-caller and get him to Austin.

4. Former Ole Miss coach and Lane Kiffin coordinator Ed Orgeron turns down Nicholls State head coaching job.

Orgeron turned around the USC Trojans last season as interim coach after Kiffin resigned, then felt shafted when the university didn’t seem remotely interested in retaining him.

But after failing to land what he transparently hoped would be a big-time head coaching job after the performance, he apparently made a promise to his family not to coach this season, preferring to wait until next year with the goal of inheriting his own program again.

Orgeron lives in Mandeville, La., not far from the Nicolls State campus. Charlie Stubbs stepped down Sunday after the team started 0-3, including a 73-7 loss to Arkansas. Rather than solidifying his status as a head coaching candidate in a truncated season, Orgeron has chosen to hold his cards and see where it leads after the season.

5. Fresno State, in need of depth at kicker and punter, holds open tryout for students.

Kicker Colin McGuire left the team to deal with personal issues, leaving Fresno State’s placekicking duties to a freshman walk-on. He and punter Garrett Swanson are the only two kickers on the roster, leaving the team in a major bind if either of them gets injured.

Fresno State responded with a campus-wide search for a backup kicker, asking students with kicking experience to meet the football coaching staff in the Josephine Theater on Thursday morning.

6. Will key Pac-12 South game feature two backup quarterbacks?

UCLA and Arizona State, both Top 20 programs, meet Sept. 25 in a pivotal division matchup in the Pac-12 South. But senior quarterback Taylor Kelly, perhaps one of the 15 best at the position in the country, will miss the game due to a foot injury, the Sun Devils announced.

Bruins starter Brett Hundley (elbow) may or may not miss the game as well. UCLA coach Jim Mora has closed all practices and restricted media availability ahead of the game. No. 12 UCLA (3-0) has won three games by a combined 18 points, risking a loss against Virginia, Memphis and Texas.

Arizona State (3-0), in the best position to capitalize if the Bruins stumble, must face ranked USC and Stanford following the game with UCLA, so Kelly’s status is crucial.

8. Texas may not want any part of Texas A&M right now, but the Longhorns have agreed to play a home-and-home with Michigan.

The games aren’t until 2024 and 2027, but still.
