Too many teams need a Safety. You culd easliy point to the Lions, Rams, Bears, Bucs, etc and a host of other teams willing to make a deal for Harrison.
From what I can see in this draft, the 33 - 66 picks are even. Vikes have the 66 pick. Two positions of critical need are met with two day one starters - and frankly when was the last time the Vikings had a real Safety? The next two safties are ranked as 3rd and 4th rounders. This was it if the Vikings wanted a safety. Hey, they got Kalil by letting the picks come to them, but they also got the safety they had move to have.
There are a lot of WR's and ILB's and cover-2 CB's available with 3rd to 4th round grades, who are going to start for the Vikings.
Nick Toon is still on the board as are a host of other WR's. I like the Nebraska CB Denard also and the Iowa WR McNutt too. They will be there in the 3rd or 4th.
