I think McD focuses on fit for the system particularly when it comes to the RB position. There were reports pre-draft about how he met with the scouting staff and provided very specific criteria for what he wants in a RB.
In his last interview, Cook specifically said he was a "perfect fit" for the Miami offense. My guess is that his fit being such perfect has been part of the discussion. I think that if this gets done it will be with an incentive laden deal that gives Cook the chance to earn closer to what he's hoping for while keeping the base closer to what Miami is hoping for.
I can agree with that. My only nit is $$. To make an extreme example, Cook wants $15mm/yr - LF wants3mm/yr. Cook is the perfect fit. LF is 'almost' perfect. How much more is Mcd willing to pay for 'perfect?' I have no idea. As a reminder, I'd love to have Cook. This, in no way, is meant to dis anyone. My only question is how much Mcd is willing to pay. If there can be no agreement on $$, Mcd makes the call when to move on.
