Don't agree, JL. 1 & Done in the Playoffs (most likely scenario) and heading into the final Contract year for Kirk (and them, IIRC). Unless they're complete idiots, and we have no evidence to support that they are, Rick and Mike will do what they need to in order to try and get the Defense back on track. Their jobs in all likelihood will depend on it.
That means jettisoning big contracts for underperformers ala Rhodes & Griff. Reiff will likely be gone too. That means the cap room should be there to re sign whomever they want.
Mac is a Slot CB who will likely want a shot at playing Outside somewhere like he did in College. Minnesota knows him better than anyone else and is the most likely to give him that shot. Probably a tweener contract that pays him the Slot CB going rate with incentives for play on the Outside. Maybe even something shorter in length so that if he performs he can get Outside CB market rate after say 2 seasons.
I favor this option and adding a veteran FA at either Slot or Outside over retaining Waynes.
Signing Harris shouldn't be hard. UDFA that got a chance with the Vikings who've steadily moved him up depth chart. And he's only been starting for what, a season and a half? Teams aren't going to be looking to break the bank for him. It will be a typical Brez Special. Kearse I could care less about. Guys like him in every Draft.
Look for two Picks in the first 4 Rounds to be D-Line and a veteran CB that won't take long to get up to speed in Zimmer's system with Mac and Harris resigning, IMO. If the Draft Picks produce this Defense is back on track next year.
