Tommy Doyle thought Iowa so nice that he visited twice. The stops occurred during a two-week period.

The Minnesota lineman dropped by the Big Ten school for a second time last week. He watched spring practice.

It’s not uncommon for prospects to take multiple unofficial visits to schools they like. They’re normally spread out over more than a 14-day period, however.

"What brought me back is that it’s a school that definitely interests me and it’s one that I would want to play for. I was just, overall, really impressed on the first visit and that’s what made me want to go back to make sure they know that I’m interested in their school," Doyle said.

The Hawkeyes are interested in Doyle. He’s on their recruiting board awaiting an offer. He hopes it comes during his camp stop at the school this summer, if not before.

"The coaching staff made a big impression how they talk about how they’re able to develop high schoolers into being grown men and into being football players and putting guys in the NFL. It was that combined with the facilities. They were obviously very amazing. The strength coach, Coach (Chris) Doyle (no relation), definitely impressed me. He’s one of the better strength coaches out there," Tommy Doyle said.

Eastern Michigan and Illinois State are on board with offers for the 6-foot-7, 250-pound Doyle. The Edina High product also reports interest from Iowa, Minnesota, Wisconsin, Northwestern, Miami (Ohio), North Dakota State and Northern Iowa.

Doyle spent most of his junior season playing defensive end. Schools such as Iowa have projected him at offensive tackle.

Uncertainty over his future position puts Doyle in a place where summer college camps will be his proving ground. He said he definitely will stop at Iowa, Minnesota and Wisconsin.

"I have to show that I’m quicker off the ball more than I am on film; that I’m continuing to work on my speed. I also need to show that I can be an offensive tackle by taking some reps in one-on-ones," Doyle said.

This year, Doyle walked away from hockey, a sport he played throughout his youth. He’s been focused on improving at football with Performance Athletix, a company started in the late 1990s by Ted Johnson.

"My junior season in high school I was primarily on the defensive side of the ball. I’ve worked a little bit with offense. For my senior year in high school, I’ll be playing on both sides of the ball," Doyle said.

"Northwestern, they originally thought that I was an offensive tackle. They’re also thinking about defensive line. Miami (Ohio), they didn’t label me at a position and they think, depending on how I grow and develop, I could be on the defensive line. Northern Iowa sees me as a defensive lineman. North Dakota State sees me as a defensive end. Some schools are looking at me more as an interior defensive lineman."

Doyle said he’s considering a marketing major in college. He’s talking with his lead recruiter at Iowa, Seth Wallace, about that program there.

"We’ve emailed a couple of times already since my last visit about coming back. I’m definitely going to be at camp there at Iowa," Doyle said.

Doyle said he would be attending Minnesota’s spring game on Saturday. He expects to be at the Nike camp in Chicago May 2.
