We should put the transition tag on Grant
I saw a post somewhere actually claiming the cost to franchise a DE is around $8.5mm. That said, it may be worth it. Without Grant, we don't have anyone to fill in. If we lose Grant DE is our number 1 priority in both free agency or the draft (and possibly both.)
I don't like creating a new position of need on defense.
That said I don't think we should seriously overpay for his sevices. That's why I think we franchise him if we can't work something out. This will give us a chance to develop some other talent at DE (or atleast get some compensation for him.)
