Kansas City Chiefs HC Andy Reid’s 2026 training camp decision is already proving to be a game-changer after a single practice
Kansas City Chiefs HC Andy Reid’s decision to bring back the rookie head start at 2026 training camp in St. Joe is already being felt. Those in attendance are getting an opportunity to set themselves up for success when the veterans arrive.
The Kansas City Chiefs brought back their rookie head start for 2026 training camp. The early returns suggest the decision is already paying dividends for Patrick Mahomes and a loaded group of first-year players.
Last season, the Chiefs opted against the three-day rookie head start that NFL teams are permitted to hold before veterans report. Andy Reid made the call because Kansas City simply didn’t have a large enough rookie class to justify the extra days. The team carried a limited number of draft picks, UDFAs, and eligible second-year players, making the head start feel unnecessary at the time.
Reid has since changed his tune. He told reporters this week that skipping the head start last year was something he regretted after the fact.
“I just thought it was necessary,” Reid said. “I didn’t like not doing it last year after I got done with it, to be honest with you. It is a good thing for the quarterbacks, and it is a good thing for the rookies coming in. We do have more numbers this year, so it allows us to get more reps, and I think that will benefit us.”
With a group of 35 participants this year, not including two players who landed on the active PUP list, the Chiefs coach felt the early window was essential for 2026.
Mahomes building chemistry with new weapons
The truth is that the biggest benefit of bringing back the rookie head start won’t just be felt by this year’s class. It also highlights what last year’s rookies missed. Guys like Jalen Royals, if he were healthy and able, would’ve benefited greatly.
Chiefs QB Patrick Mahomes got extended repetitions with a number of players, including rookie running back Emmett Johnson, during the early sessions.
Rookie wide receivers Cyrus Allen and Jeff Caldwell, along with several second-year players, are using the extra time to build chemistry with Mahomes before the full roster arrives.
Second-year wide receiver Jimmy Holiday, who spent last season on the practice squad after a strong training camp and preseason, caught an impressive red zone touchdown during practice. Holiday’s development is a reminder of how valuable these reps can be for players on the roster bubble.
Defensive rookies are also getting acclimated
On the other side of the ball, Kansas City’s young defenders are using the head start to sharpen their skills against Mahomes. The early practices have given rookies a chance to face the QB while he ramps up his workload after a knee injury.
Rookie cornerback Mansoor Delane perhaps put it best when asked about going up against Mahomes.
“As advertised,” Delane said. “He’s a great quarterback.”
For players like first-round pick Peter Woods and second-round pick R Mason Thomas, the true test won’t come until pads go on. However, the head start has provided a valuable acclimation period. The early days cover everything from timing up their walk down the hill to the practice field in the morning to getting the butterflies out before the work with the veterans begins.
“I’m super grateful for the three days,” Woods said. “I told someone earlier that the veterans, they have a standard for what they want to see from us young guys. Just coming in and being able to have some days to prepare myself to be able to mesh well with the veterans. That means a lot to me; not everyone gets a chance to do that.”
Why it matters for the Chiefs going forward
Reid’s willingness to acknowledge last year’s mistake speaks to how seriously Kansas City takes its developmental process. The Chiefs have built their dynasty partly by developing mid-to-late-round picks and undrafted free agents into contributors. That pipeline relies on maximizing every available practice rep.
The rookie head start gives young players three extra days to absorb the playbook. It gives them time to learn the routine. They also can compete amongst themselves before veterans flood practice. With a deep rookie class and several second-year players still fighting for roster spots, this year’s head start could prove to be one of the more consequential offseason decisions Reid made heading into 2026.
