MORGANTOWN, W.Va. -- When Dana Holgorsen left Texas Tech five years ago, he left behind the enduring reputation of an offense that remains in familiar form today.
The Red Raiders run a version of the Air Raid offense that Holgorsen has taught in his two seasons as the West Virginia coach and one meets the other Saturday afternoon at Jones AT&T Stadium.
Yet it's the Texas Tech defense that's most like No. 5 WVU's offense.
The Mountaineers (5-0, 2-0 Big 12) have the nation's most prolific quarterback and are No. 2 in passing offense and No. 3 in total offense.
The Red Raiders (4-1, 1-1) enter the 3:30 p.m. game (WCHS telecast) ranked No. 1 against the pass and No. 2 overall.
Texas Tech doesn't do a whole lot on defense and plays a pretty basic style, but is pretty good at the few things it likes to do.
The Mountaineers don't have a playbook on offense and run but a handful of plays during a game, but do those things quite well.
"The fact they've gotten so good at what they know and what they do is what makes it so hard," West Virginia University quarterback Geno Smith said. "They may still come out and do something unexpected and throw us off a little bit, but those guys do a real good job just playing their scheme."
Texas Tech had one of the nation's worst defenses last year and finished between Nos. 113-120 in total, scoring, rushing and pass efficiency defense.
Texas Tech Coach Tommy Tuberville hired Art Kaufman from North Carolina as the defensive coordinator in the offseason, the fourth in as many years for the Red Raiders.
They've kept things fairly simple to succeed.
"What you see is what you get from them," wide receiver Stedman Bailey said. "They really don't do anything you don't see coming."
More often than not, the defense lets the cornerbacks play man-to-man coverage and asks everyone else not rushing the quarterback to play a zone - including the safeties that are usually deep to prevent big plays.
The defenders don't fake blitzes or disguise coverages or move around before the snap to bother the offensive line or confuse the quarterback. The Red Raiders instead line up and try to get the better of the person across from them by simply doing the assignment they've done so many times before.
"It doesn't look overly complicated and it's pretty simple what they do, but a lot of times when you face a defense that doesn't do a lot, they end up being really good at what they do," offensive coordinator Shannon Dawson said.
