MANKATO, Minn. –Moritz Böhringer is feeling a lot more comfortable during his second training camp in Purple.

The receiver told media members that last year was "just too much" and "overwhelming" after the Vikings drafted him out of Germany in the sixth round.

"It was too sudden of a change because I didn't know that I would come here to the United States in general until February, so it was like my whole life changed in one or two months," Böhringer said.

He later added: "Last year I basically had to learn how to run routes in general, so you could say that last year I learned to play football."

But after spending the 2016 season on Minnesota's practice squad and receiving plenty of reps during the first two practices of camp, during which only rookies and select players participated, Böhringer is much more at ease on the field.

"It definitely helps to practice the same stuff every day and go through the routes and catch a lot of balls," Böhringer said. "The [other Vikings] receivers all tried to help me and give me tips and tell me what I need to do to become better."

When asked about his goals for these next two weeks at camp, Böhringer kept it simple: "Just try to improve like I've been doing."

His development has been noticed by Vikings Head Coach Mike Zimmer, as well.

During Zimmer's podium session following Tuesday morning's walk-through practice, he said that Böhringer has improved – from making more consistent catches to running better routes. He added that Vikings receivers coach Darrell Hazell, who was added to the coaching staff in January, has been doing well with Böhringer.

"He's catching the ball better and has a better understanding of the offense," Zimmer said of Böhringer.

Zimmer said one area of progress he's looking for from Böhringer is on bump and run.

"He's doing a better job at the top of the route," Zimmer said. "But the transition from the top of the route to accelerate out, to me, that's going to be the biggest thing. He's a little bit of a high-cut guy. He needs to be able to sink his hips and accelerate out. He didn't catch the ball great last year, so that's obviously one part. He's doing a better job with all of it. To me, those two things combined with catching the ball will help.

"He is still a ways away, but he has improved a lot," Zimmer added. "These three days have been good for him, and he's helping the younger guys a bit now, which is something he couldn't do before. The communication with the language is much better. He's got a chance."

Koehn embracing competition at kicker

Marshall Koehn is the new kid on the block for Vikings kickers, being brought in to join Kai Forbath this offseason.

Each is vying for the position on the 53-man roster, but Koehn said it's not at all a bitter rivalry.

"We're just going to come out here and compete and make each other better," Koehn said. "The results will show, and I guess we'll see what happens.

"It's a really great relationship, honestly," Koehn continued. "He tries to make me better, I try to make him better. We both know that it comes down to making kicks, so there's no reason to really, I mean, some guys are like that, but in this case, we've been really good to each other."

Koehn was 6-of-7 for field goals attempted during Monday's practice, from distances between 33 yards to 50 yards. He missed one from 39 yards out.

Koehn said reliability will be key for whoever wins the job.

"I mean, it's just going to be about the opportunities we get in preseason and how you perform out here in the scrimmages, and just day-in and day-out, how consistent you can be," he said.

Koehn, who finished his collegiate career with a field goal percentage of 77.8, believes he's become more consistent since his time at Iowa.

"I think the flight of my ball is more clean instead of an 'X ball,' you kind of call it," he added. "I think those are two things I've really tried to improve on and I think I've gotten better at."

Practice can be nerve-wracking when it's all eyes on the kicker, but Koehn said he's used to the pressure and isn't shaken.

"You've kicked so many balls in your life, and you kind of just fall back on what's made you successful, and you can't really worry about what is around you or who's watching you," Koehn said.

Coley settling in to Vikings offense

Vikings seventh-round draft pick Stacy Coley said the game is "slowing down" since his time at rookie minicamp and Organized Team Activity practices.

The receiver missed time this spring due to injury but has participated in both training camp practices since arriving Sunday. He snagged a couple of nice practices Tuesday afternoon and said it's a result of feeling more comfortable in Minnesota's offense.

"I'm just out there having fun," Coley said. "I know the playbook better, and I'm just diving into the playbook."

Coley has gotten reps both in the slot and on the outside and said he doesn't mind the stiff competition at receiver.

"That's going to just make all of us better, great," Coley said. "And we're just going to compete for a job."

Zimmer: Danielle Hunter's health has improved

The Vikings on Monday placed defensive tackle Sharrif Floyd on the Non-Football Injury list.

When asked by media Tuesday if there's any chance that Floyd would return to the field at some point during training camp, Zimmer said he "hasn't ruled him out."

"I don't know what he's going to do in training camp," Zimmer said. "We're hopeful that he's getting back.

"I don't know with these guys that are hurt, I don't know when they'll be here, or when they'll be back," Zimmer continued. "We're just trying to get them better every day. They're working real hard. I hope Sharrif gets back because he's a good player when he gets back. He's improved a lot from when he left."
