It’s probably time to pump the brakes on the hype train around one of the Kansas City Chiefs’ most compelling undrafted rookies

There’s a new buzzy undrafted rookie wide receiver on the Kansas City Chiefs. Will this one make a splash?

The Kansas City Chiefs and a buzzy undrafted rookie wide receiver. It’s a match made in heaven on the heels of several years of Justyn Ross. 

This year’s edition, Jeff Caldwell, has Chiefs fans buzzing as training camp nears. His physical tools are tantalizing — as you’d expect with a 6-foot-5 receiver who runs 4.3 in the 40. But the path to meaningful snaps in 2026 looks like a steep climb for the former University of Cincinnati pass catcher, so we should set expectations accordingly.

Jeff Caldwell’s appeal to the Kansas City Chiefs is obvious

Caldwell’s combination of size and athleticism is essentially a lock to generate buzz and, eventually, opportunity. The problem is that explosiveness and physical upside only carry you so far when the refinement isn’t there yet.

Caldwell played just one season at Cincinnati after transferring from Lindenwood University. That limited playing time at the FBS level matters and it shows up on the tape. Route running, contested catch technique, understanding option routes within a pro offense. Those layers need to develop for Caldwell, hence why he went undrafted despite being built like a Transformer with a jet pack strapped to his back.

The Chiefs aren’t hurting for pass catchers with explosiveness, either. That’s the second fundamental issue for Caldwell’s 2026 outlook. Kansas City has more established players who bring their own brand of explosiveness and carry the advantage of experience in the system.

Rashee Rice should remain a focal point of the offense as the team works to get him back on schedule as a major contributor. Tyquan Thornton emerged as a legitimate downfield threat last season, even in a low-volume role. And then there’s Xavier Worthy, who offers elite explosiveness with the ball in his hands and the ability to attack vertically, too. 

Caldwell’s best traits overlap with what those players already provide (which is a problem!). The other two receivers have already carved out roles within the offense and possess far more refinement at this stage of their careers.

The long game is the path for Caldwell

None of this is to say Caldwell can’t become a contributor for the Chiefs down the road. The measurables are real, and developmental hits at wide receiver happen across the league every year. If Kansas City can keep him stashed on their roster, likely through the practice squad, and invest time in his route tree? That would help him translate that size-speed combination into consistent production against NFL defensive backs. But let’s slow our roll.

Caldwell’s time may come. But I’d venture to bet it isn’t going to be in 2026.
