It seems like there is a league wide view of JC that doesn't see him as a shut down CB. More good than great, BUT with a great eye for the ball and great ball skills. I really want him to be on the team this season, but I can't see it happening right now. The only chance I see that happening would be a Hightower scenario where he goes and tests the market and finds that "league view" is a reality. Unfortunately it only takes one team looking to make a splash and has lots of cap room.
IMHO here is how I see it. Based on what we are hearing, Jackson's true value is in the range of $15mm/yr on a 4 year deal with 70% guaranteed. He's looking for a deal in the range of 4/yrs for $90mm. Which would be top 3 money on a long term deal.
THis would be my compromise. It would be that $60MM dollar deal as a base, with incentives that would increase the deal much close to what Jackson wants. And these incentives would be a combination of stats/games played and awards that would come to a true shut down elite CB. This way he gets paid IF he produces, and if he is just good but not great, then he'll get paid his true value.
That's the deal I'd try and work out.
