Welcome to the Extra Points, our weekly college wrap-up at Dave Campbell’s Texas Football. This is your one stop to quickly get up to date with all the most important FBS happenings in the state from Week 7.

FORT WORTH -- Texas Tech proved once and for all that this season is going to be different.

Tech had its work cut out in a Thursday night, nationally-televised tilt. The Red Raiders faced off against TCU, a team that had not lost at Amon Carter Stadium since December 2016. They also were without starting quarterback Alan Bowman and top receiver T.J. Vasher.

But to understand what exactly happened in a 17-14 – really! – win over TCU, we just have to fast forward to the final play.

With just a minute remaining, the Red Raiders forced 4th-and-1 at the TCU 47-yard line. Getting a stop would end the game. But on the other end, TCU quarterback Shawn Robinson ranks as one of the elite short-yardage runners in college football. The Horned Frogs run the ball well overall. Their receivers rank among the best in the conference.

But thanks to watching film, the defensive staff felt confident that TCU was likely to throw it. TCU lined up in base shotgun formation, which Tech countered with a 3-3-5 nickel defense. It’s a relatively safe coverage that still allows some creativity

Robinson dropped back to pass, but strongside linebacker Kolin Hill immediately blitzed and forced him left. Robinson’s athleticism was enough to turn around and reverse field back right. However, the pursuit continued and, almost by fate, the ball flew out of his hand and into the waiting arms of defensive back Adrian Frye.

“We knew they were going to throw it,” linebacker Jordyn Brooks said. “We knew he was going to scramble around, so we had guys come up the edge and get as much pressure as we could.”

It was a perfect play call that ended the game.

Robinson’s mistake decided the game. It doesn’t happen without the right defensive play call, fantastic coverage to keep the receivers occupied and resilient effort from the front seven to keep Robinson uncomfortable for a full 15-second play. That takes talent, effort and execution all at once.

“I feel like as a defense, we are a lot closer than we have been,” Hill said. “Our relationships are a lot closer. It’s easier to communicate on the field and everybody executes at a high level. You can trust everybody out there.”

Remember, Texas Tech posted the worst defensive season in college football history just three short years ago. On this same field, TCU scored 82 points and ran out of the season’s supply of fireworks thanks to the Red Raider defense. Finally, in his fourth season, Texas Tech defensive coordinator David Gibbs’ plan is starting to come together.

On the other end, this TCU stretch is concerning. The Horned Frogs have now lost three of their last four games. The one win – a 17-14 edging of Iowa State at home – wasn’t exactly impressive. Suddenly, the Horned Frogs shift from Big 12 title contender to perhaps fighting for bowl eligibility.

Robinson’s turnover issues have not gone away. The sophomore has turned over the ball 12 times in the last five games on his own. There’s only one Power Five team that has turned it over more times than TCU, and you don’t want to hear who. Sorry TCU fans, it’s Rutgers.

Games at home against Oklahoma and on the road against West Virginia are likely losses. Matchups with Baylor, Oklahoma State and Kansas State feel more like 50-50 propositions than the surefire wins they seemed to be a few weeks ago. With three losses already in the record books, the margin for error in Fort Worth is razor thin.
