Chiefs jersey number surprise may hint at major role change plan

The 2026 NFL Draft has come and gone. Now that the dust has settled on the mock drafts and fans everywhere have pivoted to film review and depth charts, the next thing before the much-ballyhooed schedule release—how did that become such a big thing?—is awaiting the assignments of jersey numbers.

Ah, yes. That hill of fan-dom that half of Chiefs Kingdom lives and dies on, and the rest could not care less about. No, jersey numbers do not affect character or on-field play, but some would argue (myself included) that a jersey number can, in some cases at least, lend to the persona of a player. Whether you idolize a certain player from the past, or if one specific number has some kind of inscrutable aura, maybe you're someone who thinks that jersey numbers have some level of effect on the game. If that's not you, this reading probably isn't your cup of tea.

Certainly some numbers speak for themselves: 42 in baseball. 23 in basketball. 56 in football. There are a handful of players whose number has become an iconic part of their respective sport, almost mythic in nature. But that's less than a tenth of a percent of athletes. For most, they pick their number and that is that.

The Kansas City Chiefs announced their newest jersey numbers on Thursday.

Much has been said about the selection of R Mason Thomas, a breakneck pass rusher whom many have predicted will slide in at defensive end on obvious passing downs. Thomas, a 6'2" 241-lb. 21-year-old, absolutely screams off the edge, and there is unparalleled excitement about his potential when compared with other defensive ends that have been drafted by this regime, even first rounders like George Karlaftis and Felix Anudike-Uzomah.

On Thursday, the Chiefs announced that Thomas, the 40th pick in the draft, will wear #34.

But here's the thing: while NFL rules regarding jersey number allocations have loosened up significantly since 2023, there are still standards that must be met. Per the NFL Operations website, defensive linemen must wear 50-79 or 90-99. So how do the Chiefs reconcile giving #34 to a defensive lineman?

It's possible that Thomas isn't being brought in to play defensive line. That same website says that linebackers are allowed to wear any number from 0-59 or 90-99, at least opening the door to the possibility that Thomas may well be tapped to replace the departed Leo Chenal as the team's SAM linebacker. The Chiefs only have Cooper McDonald at SAM in 2026, so it seems there is a move still coming at that position.

Rewind to Day 2 of the Draft: when the Chiefs phoned Thomas to let him know they were going to pick him, Steve Spagnuolo was specific to identify a name that helped lead to his selection. "[New Chiefs running backs coach] Demarco Murray had some great things to say about you," Spagnuolo said to Thomas, making reference to the coach who also made the jump from the Oklahoma Sooners to Kansas City this offseason. This is all speculation at this juncture, but it could be that Murray's input from his time at Oklahoma has an effect on how the Chiefs plan to utilize Thomas.

Time will tell whether the Chiefs think Thomas can do it. This wouldn't be the first time they selected a player and changed his position. Just last year, they selected 3-tech defensive tackle Omarr Norman-Lott and moved him to the nose. Whether Thomas stays with his hand in the dirt or is asked to take on new things will be unveiled this summer.

Here are the rest of the Chiefs' jersey numbers from this weekend's draft:
