In what turned out to be a heartening 2012 run, Vikings coach Leslie Frazier continually encouraged his players to buy into one philosophy: “Don’t ever let outsiders put limitations on what you can achieve.”

With a full buy-in to that, the Vikings used a potent combination of unity and belief to propel a 10-win season and a surprising push into the playoffs.

Now, the team heads into 2013 with heightened expectations and an understanding that the climb to the next level only gets steeper.

With roster changes still ongoing and five weeks until the team enters the draft with 11 picks, Frazier took time Monday from the league’s annual meetings at the Arizona Biltmore to discuss the Vikings’ evolution.

The key story lines …

The pitch to land Greg Jennings had as much to do with Adrian Peterson as it did with Christian Ponder.

What’s the story? Look, when you have the league MVP, you sell that. And the Vikings did so, reminding Jennings of just how dangerous Peterson is and what his presence alone does to loosen up defenses. Not that the veteran receiver wasn’t already aware. Jennings, after all, saw Peterson rack up 508 yards in three games against Green Bay last season.

As a shrewd veteran seeking an ideal fit, Jennings took inventory of the situation in Minnesota, making certain to first gain a belief in Ponder. It didn’t hurt that Vikings offensive coordinator Bill Musgrave and receivers coach George Stewart then spent significant time expressing their plans to use Jennings in a variety of ways — outside, from the slot, over the middle, over the top, etc.
