He's been asked to work as an offensive lineman and as an inside receiver with the Mountaineers, but now, in his redshirt freshman year, he's a 6-3, 255-pound blocking running back.
He spends time meeting with the offensive linemen and the running backs and he defies a true label.
"I think people have a perception that we don't use a tight end when we actually do," running backs coach Robert Gillespie said. "We put him in a three-point stance on the line and we line him up in the backfield. It adds another element and lets us play fast. When you have him in the backfield and you go no huddle you can keep him as a tight end.
"We're trying to find as many ways to take advantage of our personnel. That's the one thing that's fun about coaching in this offense. Dana wants the offense to change and adjust to the personnel we have."
The offense itself doesn't change much. As far back as his playing days at Iowa Wesleyan for Hal Mumme all the way to today, it's mostly the same, though Holgorsen's freshest and most accurate memories come from his eight years at Texas Tech with coach, and Mumme protege, Mike Leach.
The routes are basically the same and the playbook is still thin bordering on non-existent. Tempo is important and mismatches matter. But who runs the routes and memorizes the plays and hurries the tempo and makes the mismatches has changed.
WVU is recruiting tight ends like Clay and freshman Will Johnson and will play them as a tight end like Clay or as an inside receiver, like the Mountaineers plan to do with the 6-7 Johnson after his redshirt year. Don't believe in the idea of a tall inside receiver? You missed 6-4 Dante Campbell catch a 4-yard touchdown pass against JMU.
Yet there's still a stage for smaller guys like Tavon Austin and Jordan Thompson, though they must still block like they're bigger.
Perhaps most intriguing, though, is the offense's marquee position. Holgorsen has long been affiliated with quarterbacks. What Smith is doing this season is, according to quarterbacks coach Jake Spavital, better than Holgorsen's most famed pupils, Houston's Case Keenum and Oklahoma State's Brandon Weeden.
Look at the recruiting, though, and see the Mountaineers with a 2013 commitment from a dual-threat quarterback in Chavas Rawlings and an offer out and a strong push for arguably the top-ranked dual threat quarterback in 2014, D.J. Gillins.
Can't happen? Look not at the problems the pocket-passing Smith is giving teams with his mobility, but at Texas A&M. The Aggies are coached by Kevin Sumlin, who hired Holgorsen at Houston. Sumlin's offensive coordinator is Kliff Kingsbury, who played for Holgorsen at Texas Tech and was his quality control assistant at Houston. Texas A&M is starting a dual threat quarterback this season running a familiar form of the Air Raid offense.
WVU is intrigued by Smith's movement and how it affects opposing defenses and the Mountaineers don't want the possibilities to automatically end when Smith departs and is replaced by the more stationary Ford Childress or Paul Millard.
If they can get another mover, they can shake up college football again.
"We've never had really a running quarterback in the past," WVU offensive coordinator Shannon Dawson said. "It may change what other teams try to do, but we're not going to change what we do. We'll allow him freedom to make plays with his feet.
"We won't sit there and tell him not to do that, but on the same hand, we've got to be careful about him running the ball because you don't want your quarterbacks getting hit because we're always going to throw the ball first."
