As far as the answer, if you can qualify him as a "surprise" I'd say Jacoby Ford. He's been getting some love lately but he's certainly not getting a roster spot over any one of Decker, Kerley, Nelson, or Hill. Factor in another 3 Idzik draft picks and he's going to have to be a (relative) world-beater (and a healthy one at that) to make this roster. Kick return prowess alone isn't going to do the trick.
Yeah, I said this during the draft. Jalen Saunders is basically the same guy as Ford, will they see a need to carry two 5'9" speedsters? I do think they'll carry six WRs, though.
Wilson's in the last year of his deal, and seeing how Idzik works I have little doubt he'd much rather keep Wilson around to get a comp pick for the guy. As much of a disappointment as he may be to the Jets, he's still good enough (and CB play throughout the league bad enough) to get signed next offseason.
Besides, you can't count on Patterson staying healthy and Wilson's the only other guy in that group with any significant experience.
This is what I think, too. Wilson is a competent nickel, for all the sh*t he gets here, and the Jets still have questions that need to be answered as far as who'll emerge as the starter opposite Milliner. He's not expensive to carry, and he's decent depth. And there is a real possibility that he'd be good for a late comp pick, too.
