You are correct. The Vikings will never be accused of being smart about things like this.I could see the Bucs leaking that so someone will jump in front of the Vikes and the Bucs get more draft capital.
If the Vikes do take Willis at 34 it might be the dumbest move ever. If they were going to take Willis do it at 32 so you get the 5th year option and then take Cine at 34.
