It will probably cost the jets 1/4 mill to find out.
2 year contract a 250,000 SB and vet min (about 650,000 for a 4 year vet)
and 50,000 for every game he plays for the first year 2,000,000 for the 2nd.
If he does not hold up thru camp, the 1/4 mill is kissed off. If he makes the roster but is just the back up he is cheap. and if you wan to let him go year two it is a 125,000 cap hit.
I think your going to have to give him something up front if you want to be sure to get him. 20 teams will let him come into camp for a walk on.
