Expert compares rising Chiefs UDFA WR to Lions legend Calvin Johnson

[ASFN Admin]

The Kansas City Chiefs may have found a true diamond in the rough by signing former Cincinnati Bearcats wide receiver Jeff Caldwell as a free agent after the 2026 NFL Draft.

One metric that modern draftniks use to evaluate a player's athletic profile is "Raw Athletic Score," which combines several variables to determine a score on a 0-10 scale.

Given Caldwell's outstanding athleticism, it should come as no surprise that the Cincinnati standout scored a perfect 10.0 on the RAS scale, garnering comparisons to Detroit Lions legend Calvin Johnson, who also achieved a perfect mark and shares some striking similarities to Kansas City's rookie on paper.

Something I missed due to all those site issues was that Jeff Caldwell's average, which was below Calvin's the last time I checked, actually ticked up and PAST the long standing 10.00 RAS wide receiver! We ended up with a new top score at WR, didn't see that coming! pic.twitter.com/ORmdOoCYlg

Caldwell was never considered to be a top pass-catcher in his class, but he possesses rare athletic traits that made him stand out in pre-draft testing.
