Liam Coen spent his first year in Jacksonville trying to make Thomas into a possession X, a guy who wins at the catch point on in-breaking routes -- and came away deciding that isn't his player. Per Cameron Wolfe, the plan for this season flips it: Thomas moves back outside as a true X, running the kind of vertical route sheet Coen once gave Brandin Cooks and Sammy Watkins in Los Angeles, with the underneath and possession work shifted to Parker Washington. That's a coordinator admitting a scheme mismatch and correcting it, not a hope.
What made Thomas dangerous as a rookie was pure closing speed before the catch -- defenders lose him vertically, not at the top of a route. Coen tried to add layers last year, pushing him deeper downfield and into more contested, one-on-one situations along the sideline, and the traits that made him special didn't carry over to that job. He also came into the year nursing a hand injury from Week 1, which is a real explanation for hands that got worse, not just an excuse. He's spent the offseason on it -- catching off a JUGS machine after every practice, digging his hands through a bucket of sand -- specifically to fix the part of his game that broke down.
The honest problem is that not all of the decline was schematic. A receiver who caught most of what came his way as a rookie caught barely half of it last year, and that's on hands, not play design. He also missed time to ankle and shoulder injuries on top of the wrist issue, so a full bounce-back requires him to be both healthy and actually fixed at the catch point -- not just relocated to an easier job.
Marvin Harrison Jr. is the other true outside X here, a bigger frame who's supposed to win on size instead of separation -- except drops have dogged him since his own rookie year, the same disease Thomas is trying to cure. The difference is what's under each of them. Thomas is playing for a coordinator who spent a year finding out what doesn't work and rebuilt the route sheet around what does. Harrison is throwing to whoever's left at quarterback in Arizona now that Kyler Murray is gone and Jacoby Brissett is running the show -- a receiver with a worse passing situation and no rookie-year proof, like Thomas has, that the talent shows up when the offense is right.
