Chiefs Sign Undrafted WR Jeff Caldwell, a 10.00 RAS Standout

Kansas City is betting on rare traits to add upside at a thin receiver spot.

Overview

  • Kansas City signed Jeff Caldwell as an undrafted free agent after the draft to compete for a roster spot at wide receiver.
  • At the NFL Combine he ran a 4.31 40 with a 1.48 10-yard split, jumped 42 inches vertically and 11 feet 2 inches in the broad jump, producing a perfect 10.00 Relative Athletic Score that ranks second among 3,926 receivers since 1987 behind Calvin Johnson.
  • Caldwell is 6-foot-5 and 216 pounds and moved from FCS power Lindenwood, where he was highly productive, to Cincinnati in 2025, finishing with 32 catches for 478 yards and six touchdowns against tougher competition.
  • Scouts praise his speed and size but flag raw route-running and drops, and he now works under new Chiefs receivers coach Chad O’Shea, who is tasked with sharpening his technique.
  • The Chiefs focused their draft on defense and added only one receiver in the fifth round, so Caldwell enters a room led by Rashee Rice and Xavier Worthy with opportunity but no guarantees in an offense that has had mixed results developing wideouts.
