The Vikings used a pair of seventh-round draft picks on r

eceivers. So far Brett Jones Jersey , they’re apparently showing why they lasted until round seven.Coach Mike Zimmer isn’t happy with the performance of Dillon Mitchell and Olabisi Johnson.“They haven’t been precise enough,” Zimmer said Sunday, via Chris Tomasson of the . “They need to get their rear end in gear.”Typically, seventh-round picks face an uphill climb to make the roster. The Vikings gave Mitchell and Johnson slotted signing bonuses of $80,000 and $74,000 Dan Bailey Jersey , respectively, to secure dibs on the ability to assess whether they may end up being good enough to make it or, at a minimum, whether they could slip through waivers and land on the practice squad.If they don’t step it up, that will be the best-case scenario for Mitchell and Johnson. If they do step it up, the best case entails a chance to compete and contribute on a top-heavy depth chart with plenty of question marks behind Adam Thielen and Stefon Diggs. On the surface Tom Compton Jersey , it looks like a desperate move. But that doesn’t mean the firing of Vikings offensive coordinator John DeFilippo won’t work. Indeed, six Decembers ago, another team that wears purple made the same move, on almost precisely the same day.December 10, 2012. Ravens coach John Harbaugh fired offensive coordinator Cam Cameron, replacing him with Jim Caldwell. And the Ravens went on to win the Super Bowl.It didn’t look like it would go that way. After a loss to Washington dropped Baltimore to 9-4 Alexander Mattison Minnesota Vikings Jerseys , the Ravens lost two of three with Caldwell running the offense. But 10-6 was still good enough to win the division, and the fourth-seeded Ravens beat the fifth-seeded Colts at home before going on the road to beat the top-seeded Broncos in double overtime, the second-seeded Patriots in the AFC title game, and the 49ers in Super Bowl XLVII.The Vikings will need to do a lot better than 1-2 to make it to the playoffs. They likely will need to run the table. And if they fail to quality, don’t be shocked if coach Mike Zimmer becomes this year’s inevitable surprise firing.Although Zimmer is a great coach and a brilliant defensive tactician, he hired DeFilippo. And Zimmer didn’t do enough to get DeFilippo to run the offense the way it needed to be run Minnesota Vikings Jerseys 2019 , designing plays and concepts aimed at getting the most out of the players they have, and at exploiting the weaknesses and tendencies of every defense they face.The question now becomes whether interim offensive coordinator Kevin Stefanski can do enough, with Zimmer’s assistance and support, to kick-start an offense that has failed to properly complement one of the best defenses in football. It starts Sunday against the Dolphins, followed by NFC North contests against the Lions and Bears.
