MANKATO, Minn. –Jerick McKinnon said it's a blessing to learn from Adrian Peterson every day.

On Monday, McKinnon had the chance to pick the brain of another talented running back – except it took him a minute to recognize him.

"He had on a hat and glasses, I didn't know," McKinnon said, laughing. "I'm out here paying attention to special teams, Coach Zim' calls me over [and] asked me if I know who it is, and I can't even see his face […]. He took of the glasses, and then I was like, 'OK, it's Marshall Faulk.' "

Faulk racked up 12,279 rushing yards, which currently ranks 10th all-time in NFL history, over the course of his 12-season career. Now an NFL Network analyst on NFL Total Access, he made a stop at Vikings training camp to interview a handful of players, including Peterson and Teddy Bridgewater.

Although McKinnon met Faulk briefly at the NFL Scouting Combine in 20

14, he appreciated the chance to talk candidly with the Hall of Famer he admired growing up.

"Any time you get to learn from one of the best, it's definitely an opportunity," McKinnon said. "I just tried to pick his mind – ask him questions and take what I can from him.

"We talked about some pass pro technique – about some pass sets and how to approach defenders," McKinnon added. "Just the little things. It definitely helps, coming from a guy like that with that experience and of that magnitude."

Zimmer's to-don't list

Every Vikings player went to the turf.

Vikings Head Coach Mike Zimmer had seen enough and ordered a round of punitive push-ups during Monday's practice.

Earlier in the day, Zimmer hadn't liked the way the offense approached a series in walk-through, and he had them re-start from the beginning. The list of grievances climbed as the day progressed.

"We fumbled snaps, we jumped offsides; receivers jumped offsides," Zimmer began during a session with beat writers before pausing to remove a piece of paper from his back pocket, then continuing on his list.

He also said "a running back went the wrong way twice. We screwed up a fourth-and-20."

The miscues during the sessions that followed an off day for players were in contrast to a camp that's featured mostly crisp days.

"It's been pretty good. Today wasn't the best day," Zimmer said. "We have to do better than we did today, but for the most part, camp has been good."

1-on-1s still strong competition

There was plenty of individual competition at Monday's practice, especially when members of the Vikings offense worked on their pass protection skills against a bevy of defenders.

The first drill pitted running backs, fullbacks and tight ends against blitzing linebackers and safeties.

Each side of the ball earning bragging rights at time, but here are a few noteworthy battles from the drill:

Rookie tight end David Morgan kept linebacker Jake Ganus at bay before rookie linebacker Kentrell Brothers executed a swim move to get past fullback Zach Line.

Tight ends Kyle Rudolph, MyCole Pruitt and Kyle Carter all were strong against the rush, as was running back Adrian Peterson.

Safeties Andrew Sendejo, Anthony Harris and Antone Exum pressured "quarterback Pat Shurmur," the Vikings tight ends coach, as did linebackers Chad Greenway, Audie Cole and Terence Plummer.

Shurmur had a good laugh when he got tripped up during a battle between Rudolph and Sendejo.

Minnesota's offensive and defensive lines then went at. Center Joe Berger was strong at the point of attack while Matt Kalil pushed Everson Griffen out of the pocket on one instance.

The defense had their moments, too, as Tom Johnson, Kenrick Ellis, Scott Crichton and Danielle Hunter likely would have had sacks on four straight plays.
