DT, slot corner, and possibly RB if Murray doesn't take a pay cut.
Whether that DT is Suh or Richardson, or a lower cost option, I'll leave to the capologists. But we need someone there who can rotate in and provide starting competition for Jaleel Johnson. I don't think you want to gamble on a rookie in that rotation.
Pretty sure the NFCC disaster is why the Vikings are looking to upgrade their inside corners. Not sure what's going on with Mack, and I think I heard that Newman is retiring? Not sure. In either case, we need better play from our 3rd and 4th corners.
Then draft the OL, some LB depth, another RB and a "move" TE and we should be set. ASJ is available via FA if we want to go down that road. Recovering alcoholic I think but In terms of size speed hands, there aren't many better.
