Clothes to make women 'football literate': Arian Foster   

Houston Texans star running back Arian Foster may be the NFL's "Renaissance man," but his wife, Romina, is the entrepreneur of the family.

Her business claims to have something that can help boost the football IQ of females: clothes.

Romina started COVU, a clothing line that draws its designs from teams across the league. Foster told CNBC's "Squawk Alley" on Friday that Romina found a large market demand for women's clothes they could wear not just on game day, but every day.

"She started wearing [her own clothes] to the games, and the reception she got from the women around the stadium was beyond her expectations," Foster said. "She started selling it online and she sold over $1,000 her first day, and she said, 'All right, I have to do this.' "

Her clothing line aims to be fashionable, but also looks to help women understand the game better, Foster said. "She's in the privileged position of being married to an [NFL] player," he said while holding up a garment with the schematics of the Cover-2 defense, a scheme that utilizes 2 safeties in deep coverage.

"A lot of the women who love football don't have that knowledge, so she wanted to share that with women."

Foster also addressed some of the controversial headlines surrounding Sunday's Super Bowl, including Seattle Seahawks running back Marshawn Lynch's behavior with the media. "I don't think [Lynch] should have to talk to the media," Foster said. "Everybody says it's a part of your job because it's in your contract, but I don't think it should be in [it]."

Foster also said that, while he believes the New England Patriots will win professional football's most important game, he believes the team playing its best collectively will be victorious. "No matter what, whoever is going to win [will] play the best collectively," he said.

The former University of Tennessee Volunteer also shared his thoughts on the scandals surrounding fellow NFL running backs Adrian Peterson and Ray Rice. "They made pretty bad mistakes," he said. "I don't condone that, but I'm very empathetic towards them because I grew up in a domestically violent home."
