The Ringer has Watkins as his comp.

“ The Chiefs’ passing offense has run heavily through the team’s top two receiving targets in Travis Kelce and Tyreek Hill over the past couple of years, leaving an assortment of role-playing pass catchers rotating in as Patrick Mahomes’s tertiary option. But Sammy Watkins is now in Baltimore, and the likes of Mecole Hardman, Byron Pringle, and Demarcus Robinson have all failed to show much consistency or dependability in the team’s passing game. That could create an opportunity for the team’s fifth-round pick, Powell.
The four-star recruit was a late bloomer at Clemson, playing a reserve role his first four years there before breaking out as a redshirt senior, grabbing 53 catches for 882 yards and seven touchdowns in 2020. My pre-draft pro comparison for Powell was, interestingly enough, Sammy Watkins; he’s big, physical at the catch point, can stretch a defense deep, and offers some big-play potential―so when the Chiefs grabbed him as a Watkins replacement, it did pique my interest. He’ll have to really impress coaches in the preseason to leapfrog Hardman, Pringle, Robinson, and a handful of others, but if he can show consistency as a route runner and the ability to win on the outside when given the chance, he could earn a role as the team’s no. 3 receiving option sooner rather than later.
