How the Chiefs' offense evolved without Tyreek Hill

The Kansas City Chiefs sent shockwaves through the league in March 2022 when they traded Tyreek Hill to the Miami Dolphins for a package of draft picks and then immediately turned around and used the cap room to reshape their receiver room. Suddenly, a quarterback who had built much of his highlight reel on Hill's elite speed found himself without the deepest, most vertically threatening corps he had ever worked with. The question across every bar from Adelaide to Brisbane was simple: could the offence still stretch the field without its fastest weapon?

What followed across three seasons was a quieter, more methodical transformation. Patrick Mahomes still produced at an MVP level, but the route concepts, the personnel groupings and the rhythm of the offence changed in subtle but measurable ways. The Chiefs leaned heavier on motion, on 12 personnel with two tight ends, on Travis Kelce in the slot, and on a committee of possession receivers who prioritised spacing and run-after-catch work over raw speed. The evolution offers a useful case study in how modern NFL offences adapt when their identity player leaves.

From vertical fireworks to a controlled burn

During the Hill era the Chiefs ran a fairly standard 11 personnel base and Hill aligned outside on roughly 80 per cent of his snaps, often one-on-one on the boundary. Andy Reid built a great deal of the playbook around clearout concepts, posts and over routes that cleared space for Kelce underneath and isolated Hill in space. Mahomes' average depth of target hovered around 8.5 to 9.0 yards, and the offence routinely posted explosive plays of 20 yards or more at a top-five rate.

When Hill left, Reid did not chase another vertical speed merchant. Instead he signed JuJu Smith-Schuster on a one-year deal, drafted Skyy Moore and traded for Kadarius Toney. The plan was less about replicating Hill's speed and more about replicating his role with different body types. Smith-Schuster operated as a chain-mover, Toney as a manufactured-touch specialist and Moore as a depth piece who could eventually develop. The cap savings also allowed Kansas City to extend Chris Jones and invest in the offensive line, signalling that the team believed in a more balanced, less aerial-dependent identity.

The early returns were bumpy. Through the first six weeks of 2022 the offence ranked outside the top ten in explosive pass rate and looked ordinary against man coverage. Yet the underlying numbers told a different story. Mahomes' average time to throw dropped by nearly half a second, his completion percentage climbed and the offence began generating more first downs on early downs than it had in any Hill season. Kansas City was simply doing its damage differently.

A new personnel base and the rise of 12 personnel

Below is a comparison of the Chiefs' offensive shape across the three years before and after the Hill trade.

Metric 2019-2021 (Hill era) 2022 2023
11 personnel usage ~72% ~58% ~54%
12 personnel usage ~18% ~30% ~34%
Average depth of target 8.7 yds 7.4 yds 7.1 yds
Explosive pass rate 16.2% 13.1% 14.8%
Run play percentage 38% 45% 47%
Mahomes' completion % 66.3 67.1 69.3

The shift toward heavier personnel changed everything. With Travis Kelce and a second tight end on the field, defences had to pick their poison. They could keep a base package in to stop the run and surrender easy completions in the zone, or play nickel and risk getting gashed by Isiah Pacheco and Jerick McKinnon on the ground. Kansas City's red-zone touchdown rate climbed from 65 per cent in 2021 to over 73 per cent in 2023 largely because the run game and play-action created natural leverage inside the 20.

Marquez Valdes-Scantling replaced Hill as the boundary deep threat, but his role was more selective. He averaged only 4.2 targets per game but produced a yards-per-reception figure north of 16 because Reid dialed up shot plays specifically for him. That kind of role compression, one specialist deep threat supplemented by a stable of possession and underneath weapons, became the new template.

How Mahomes reshaped his game

Mahomes' evolution as a processor is the underrated story. During the Hill years he was famous for improvisation, scrambling right, heaving cross-body throws and turning broken plays into miracles. Without a true Hill-level contingency plan, Mahomes cleaned up his mechanics, settled into the pocket more often and trusted his pre-snap reads. His sack rate fell from a career-high 8.6 per cent in 2022 to under 5 per cent in 2023 even as he held the ball longer on designed shots.

The pre-snap motion rate also jumped, partly as a response to the loss of raw speed. Mahomes used orbit and shift motions to identify coverage shells, to create natural pick routes for his underneath receivers and to give Pacheco clearer run lanes. Coaches often talk about a quarterback's eyes being his most important weapon, and in Kansas City the offence became a clinic in disguise and eye control.

Perhaps most importantly, Mahomes leaned more on Kelce than at any point in his career. Kelce's target share climbed from roughly 22 per cent in 2021 to over 28 per cent in 2023, and his average depth of target dropped because he was being deployed as a true slot receiver against linebackers and safeties rather than as a vertical matchup threat. It was a quieter version of Kelce, but it was also a more efficient one.

Fantasy ripples across Australia and beyond

The downstream impact on fantasy football was significant, particularly for the growing number of Australians running dynasty and redraft leagues through the season. Players who had quietly been productive as Hill's sidekicks suddenly had the volume to themselves, while Mahomes himself moved from a boom-bust QB1 to one of the safest weekly starters in fantasy.

Key changes to track in your leagues:

For managers playing on platforms like ESPN Australia or through the league tools at fantasy football hubs, the lesson was that offensive evolution is rarely linear. Target share, not just talent, drives fantasy production, and the Chiefs' post-Hill passing tree was a study in redistribution rather than loss.

What the Chiefs' experiment teaches the wider game

The Kansas City transformation has become a reference point for coaches around the NFL. Teams that rely heavily on one dominant receiver, think of the Cowboys with CeeDee Lamb or the Bengals with Ja'Marr Chase, are quietly studying how Reid phased out Hill without missing a playoff beat.

The key takeaways for offensive staffs and curious fans:

For Australian viewers who tune in through Foxtel or Kayo Sports, the changes have been subtle on a casual broadcast but obvious on All-22 tape. The Chiefs still throw for 280 yards a game, but the shape of those throws is shorter, the routes are layered, and the running game sets up everything else. Watching the offence evolve has been, in many ways, a free coaching course for fans who want to understand how modern NFL systems adapt. Many of the spread concepts Reid borrowed in 2023 trace back to college football systems that have flooded the league over the last decade, with coaches like Eric Bieniemy and later Matt Nagy bringing Air Raid and Run and Shoot ideas into the professional game.

The next phase will be telling. With Rashee Rice developing into a true WR1 and the tight end room restocked through the draft, Kansas City may shift back toward a more spread, more vertical identity. But the 2022 and 2023 seasons proved that an offence built around motion, run-pass balance and tight end leverage can win a Super Bowl too. The Chiefs showed the league that losing a generational speedster does not mean losing an identity, and that flexibility itself can become the identity.
