Vikings 4 Downs: Barr, McKinnon, Munnerlyn, Hattiesburg

Every Monday morning during the offseason we'll take four questions from Twitter for our weekly mailbag using the #VikingsST hashtag. A day behind this week but, nevertheless, here it is.

Tough to tell say because we haven't seen Barr since rookie minicamp, but I don't think he'll be strictly limited as a situational pass rusher. Perhaps it's how his role begins as he continues to develop and improve in coverage. There was noticeable improvement in that area from his junior to season year in that area and enough to be optimistic that Barr could develop into a good all-around linebacker over time despite the lack of experience

But there's no question his biggest strength after playing linebacker for two seasons at UCLA is rushing the passer. We'll have a better understanding of how the Vikings plan to use him next week during minicamp, but Barr can rush off the edge at linebacker or stick his hand in the dirt at end if necessary at 6-5 and 255 pounds.

Running back Jerick McKinnon is the only unsigned rookie for the Vikings, who quickly struck deals with their other nine draft picks. The holdup likely is due to money. Panthers guard Trai Turner received four years for $2.79 million with the 92^nd overall pick, while Ravens tight end Crockett Gilmore, the 99^th overall pick, got a four-year deal worth $2.90 million.

McKinnon, the 96^th overall pick, is one of five players unsigned in between Turner and Gilmore. The draft slots were thrown off a bit by Gilmore's contract, but McKinnon isn't missing any reps. McKinnon has been at all the OTA sessions so far.

Yes, and it will probably be Captain Munnerlyn. The other option, Josh Robinson, has missed OTAs as a precaution according to Vikings head coach Mike Zimmer. Not to say that dismissed Robinson but the plan since the Vikings signed Munnerlyn was to play the same role as Antoine Winfield. Munnerlyn will likely start as the outside corner and shift to the slot in nickel situations with either Robinson, or another cornerback, on the outside.

There's been some pretty good battles between Munnerlyn and wide receiver Cordarrelle Patterson during OTAs so far. Munnerlyn also said last week that he's trying to be a mentor to some of the younger corners, like Rhodes.
