San Diego State coach Sean Lewis’ installation of the “AztecFAST” offense has been aided by two transfers who are very familiar with his system.

One of them is running back Marquez Cooper, who played for Lewis at Kent State from 2020-22.

The other is tight end Michael Harrison, a graduate transfer from Colorado who blossomed last season with Lewis as his offensive coordinator.

The 6-foot-3 Harrison, who converted from wide receiver to tight end before the 2023 season, had 31 receptions for 284 yards and five touchdowns last year for Colorado.

At San Diego State, the former CU walk-on will pair with USC transfer Jude Wolfe to give the Aztecs potentially one of the best tight combos in school history.

“They’re stepping into a room at San Diego State that has a lot of tradition,” said SDSU senior offensive analyst Ryan Lindley, who is working with the tight ends this season.

Lindley mentioned recent tight end standouts like Gavin Escobar, Daniel Brunskill, David Wells, Kahale Warring and Daniel Bellinger before reaching back to the 1980s and Rob Awalt. All of them went on to play in the NFL.

“I try to remind them weekly in camp that this is a (position) group that’s had a lot of tradition and a lot of success here,” Lindley said. “They’ve got big shoes to fill.”

Lewis said Wolfe and Harrison “give us some real position versatility. Mikey’s familiarity with the system, his background, more of a wide receiver and his feel in space, and then Jude, a little more mass. They have a thirst for the game.

“Both Jude and Mikey, they’re competent across the board in all the skills they need to have. … those kinds (of tight ends) can be cross trained, almost like Transformers, where one play they’re in-line tight ends, another play one’s in line and one’s detached. It just causes stress for the play call on the other side.”

Wolfe enrolled at the start of the year and acclimated himself during spring football. Harrison arrived just two months ago, but already is making an impact.

Here are five questions with Harrison:

What was it about Sean Lewis that made you want to follow him here?

Harrison: “I think he understands my skill set. With our games last year, he did a good job play calling to my strengths in certain situations. That’s something I valued.

“We had a good relationship on and off the field. That was important going into my last year of eligibility, really, wanting to stay in the same offense for more than one year. Over four years at Colorado, I would say I was never in the same offense for more than one year. Having a coach that, obviously, believed in me and was play calling to my strengths, that’s something as a player that you want to stay in for more than one year in a row.”

What do you see from SDSU’s quarterbacks, with AJ Duffy, Danny O’Neil and Javance Tupou’ata-Johnson all in the mix to be the starter?

Harrison: “It’s a good battle right now. Obviously, it’s hard to pinpoint who’s on top right now. There’s definitely a good battle between the three of those guys … They all throw a good ball. I have no complaints with who is throwing me the ball. There’s certain times, even in one-on-ones, I don’t know who’s throwing me the ball. There’s consistency with who’s back there. That’s what you want at this point in camp. I’m confident we’re going to get the best guy out there.”
