The Jets can use Jeremy Kerley and Eric Decker in two-receiver sets while putting Kerley in places where he's most effective -- i.e., the slot. OC Marty Mornhinweg has a myriad of ways to attack, especially with the addition of rookie Jace Amaro, a "flex" tight end who can line up just about anywhere.
The idea is to put the best players on the field, so, no, the Jets won't force a receiver into action simply to have a traditional starting lineup. Chances are, it'll be a committee approach, with Decker and a host of role players -- unless, of course, someone steps up in training camp and blows away the competition.
Kerley has been fantasy-relevant as a WR5-type for the last two seasons and may benefit from the attention that Decker will draw as the team's WR1.
