With that in mind, think about this. Wilson is slated to make 1.5 mil this year. There is no denying his next contract will get him generational money, at least something like Cam Newton money. From a business perspective, why on earth would Wilson play this year for 1.5 mil, risk career ending injury, when even if he did not play this year, it would not significantly lower his projected income in the years ahead?
Seattle is a team built to win now, can they afford to play this game with Wilson? It is in Seattle's best interest to sign him now as well, and to spread some of the cap hit over this year (projected 10 mil cap space left this year). It only gets worse looking down the road for Seattle in regards to cap space. This is about as opposite as the AP situation as you will find. With those things in mind, Wilson most certainly does have leverage. Even if Seattle went the Exclusive franchise tag route after the holdout, reports now have that figure to be close to 25 mil for 2016, and the moment that make that designation, it is fully guaranteed.
As you can see, as long as Wilson is content on remaining a Seahawk, he holds significant leverage.
