Spreading the Ball

Chiefs with TD Receptions
Hill
Kelce
Conley
Watkins
Sherman
Harris
Hunt
Robinson
Thomas

That's 9. The record in a season is 13 (Falcons.)

Chiefs that have Receptions but not TD Receptions
Ware
Williams
Kemp

Chiefs that have Rushes but not TD Receptions
Mahomes

At this rate, decent odds that Ware gets a TD pass, Williams could get one too eventually. Kemp is unlikely. Mahomes to Mahomes requires a fluke batted ball, but Kelce to Mahomes is in play.

Chiefs used to use Dontari Poe on the offense, so you never know, but it's going to be hard to find 13 players to catch balls.
