After the Vikings picked Mike Hughes with the No. 30 pick in last week’s NFL draft, head coach Mike Zimmer said a team never can have too many cornerbacks.

Following the addition of Hughes, Zimmer got another intriguing corner for his collection in undrafted free agent Holton Hill, who had been projected by some as a mid-round draft pick. He fell out, mostly likely, because of failed drug tests at the University of Texas that resulted in his suspension for the final three games of last season.

Zimmer said he will be given a fair opportunity with the Vikings.

“If he comes in here and does what we ask him to do, he’s got a chance,” Zimmer said Friday, the first day of a three-day rookie minicamp at the Vikings’ new Eagan practice facility.

There’s no question Hill has talent. Regarded as a top-notch tackler, he is athletic and has good size at 6-foot-2, 196 pounds. On Friday, Hill denied a Bleacher Report story alleging he failed a drug test at the NFL Combine in February but also acknowledged past transgressions.

“You make mistakes in the past, but you’ve got to just move on in life, build and just grow from there,” he said.

The Vikings interviewed Hill at the combine and brought him to the Twin Cities in early April for a pre-draft visit but didn’t draft another cornerback after taking Hughes and the end of the first round.

Zimmer said the Vikings did their research on Hill and doesn’t have much concern about his character.

“We’ve talked with every one of his coaches he has ever had in his entire life, I think,” Zimmer said. “We’ve talked to a lot of people at the University of Texas, and we feel comfortable with the situation. But it’s about the opportunity and what he does with that opportunity is up to him.”

Hill is an aggressive player with many of the traits Zimmer likes in cornerbacks.

“He’s a good football player,” Zimmer said. “Big, fast, tough, good tackler. … We’re excited.”

Hill said he’s not bothered by going undrafted. Related Articles The Loop Fantasy Football Report: Week 3

“I kind of wasn’t surprised,” he said. “I’m just happy I got the opportunity to be here. … It’s an amazing feeling just being out here, having the opportunity to compete for a spot on the team.”

Hill said he chose the Vikings from among “five or six” teams that showed interest, and pointed to their strong defense as one reason.

“They were the No. 1 defense last year (in the NFL),” he said. “Great coaching staff, great players on the team. It just seems like a real good fit for me to come in and learn and develop.”

Hill called Minnesota’s cornerbacks, which include Xavier Rhodes, Trae Waynes and Terence Newman, a “very strong” group, adding he hopes to “mimic their game” once organized team activities begin May 22.
