Leslie Frazier and the Minnesota staff have used this offseason to take a close look at backup Toby Gerhart, who could carry the load earlier this coming season. The Vikings are hoping that All-Pro running back Adrian Peterson will be healthy enough to play in Week 1, but nothing is guaranteed. "(Gerhart's) still a developing guy," Frazier said. "And there are some things we're going to find out in these OTAs. Before we send him home and come back to training camp, we'll give him a prescribed weight. But we wanted to take a look at him at where he is right now and just see how it would affect his quickness. Because there's a very good chance he's going to have to really carry the load early on."
