Remember, Decker has mostly worked in the slot this year. That is Kerley's area of specialty.
Devin Smith will do some things in this game, but it's his NFL debut. Hard to expect a lot out of him. And I don't think the Jets' coaches really are. In terms of the tight ends, the Jets lost a potentially big asset when Jace Amaro suffered that season-ending shoulder injury. Jeff Cumberland just isn't a great receiving threat.
Todd Bowles mentioned Thursday that he's asked Cumberland and blocking tight end Kellen Davis "to do a lot of blocking thus far." With Brandon Marshall and Decker catching passes, the Jets haven't needed Cumberland in the passing game. That could definitely change this week, but I don't think you'll see a lot of targets for him.
It looks like Kerley will benefit the most if Decker misses the game, and it looks like a good matchup on paper, but the Eagles defense hasn't been horrible the first couple weeks. Still, Kerley would be a bit of a risky play, but perhaps a better choice than Smith who looks like he'll make his debut but won't be a huge factor.
