🏈 The Kansas City Chiefs’ backup quarterback battle is already taking shape — and right now, Justin Fields appears to have the clear edge.
With OTAs wrapped up and mandatory minicamp beginning on June 9, attention has turned to who will sit behind Patrick Mahomes during one of the most important seasons of the Chiefs’ modern era.
Fields entered the offseason as the expected QB2 after Kansas City made the surprise move to trade for the former Chicago Bears, Pittsburgh Steelers and New York Jets starter.
But when LSU quarterback Garrett Nussmeier unexpectedly fell to the Chiefs in the draft, the competition became more interesting.
Now, after the first stage of offseason work, early reports suggest Fields is comfortably ahead.
🔥 That matters because Mahomes’ health remains the biggest storyline in Kansas City.
The Chiefs superstar is still working his way back from a serious knee injury, and while there is optimism he could be ready for Week 1, nothing is guaranteed.
If Mahomes needs more time, the backup quarterback may not just be holding a clipboard.
He may need to start a game or two.
That makes the QB2 decision far more important than usual.
And based on what reporters have seen at OTAs, Fields looks like the man most ready for that responsibility.
Speaking on the 41 is the Mic podcast, the pair explained that Fields is much further along in learning and executing Andy Reid’s offense.
That should not be too surprising.
Fields has real NFL starting experience.
He has faced live defenses.
He has dealt with pressure, playbooks, speed and weekly preparation at the professional level.
Nussmeier, by contrast, is still at the beginning of his NFL development.
⚠️ The rookie’s early struggles appear to be technical.
Jacobs said Nussmeier is still working through his mechanics and footwork, and those issues have shown up in practice.
The biggest problem has reportedly been accuracy on throws around 15 to 20 yards downfield.
According to the reporters, Nussmeier has had trouble keeping the ball on target, often sending passes too high.
Jacobs even joked that the rookie has been testing receivers’ “vertical rating” with some of his throws.
It was a lighthearted line, but the message was clear.
Nussmeier has work to do.
📌 Derrick also noted that Nussmeier has some bad habits from college that need to be corrected.
That does not mean the Chiefs are already disappointed in him.
It means he is exactly what many late-round rookie quarterbacks are: a project.
Kansas City likely drafted him with patience in mind.
The team does not need Nussmeier to be ready immediately if Fields can handle the backup role.
Instead, the Chiefs can focus on rebuilding his technique, improving his footwork and teaching him the timing of Reid’s system.
That kind of development takes time.
🌟 Fields, meanwhile, seemed to finish OTAs on a much stronger note.
Derrick said the final few series he saw from Fields were the best the quarterback had looked so far in Kansas City.
Jacobs agreed, noting that Fields appeared more comfortable when the Chiefs allowed him to use play action and move around.
That is where Fields has always been at his best.
He is not a traditional statue-in-the-pocket passer.
He is dangerous when he can move, extend plays and force defenses to account for his legs.
⚡ That mobility gives Kansas City something very different behind Mahomes.
Fields’ speed can change the structure of an offense.
If he has to play, defenses must prepare for quarterback runs, rollouts, play-action movement and broken-play scrambles.
That does not mean he can replace Mahomes.
No one can.
But Fields gives the Chiefs a veteran backup with a unique skill set — and that could be valuable if Kansas City needs to survive a short stretch without its starter.
🎯 One of the most encouraging signs was Fields’ timing with Xavier Worthy.
Jacobs described multiple deep connections between Fields and the speedy wide receiver, with throws travelling around 35 to 50 yards in the air.
Even more importantly, Fields reportedly hit Worthy in stride.
That is the kind of detail coaches love to see.
A backup quarterback who can connect on timing routes with one of the team’s most explosive receivers gives the offense a chance to stay dangerous.
It also shows Fields is beginning to understand the rhythm of Kansas City’s system.
👀 There were early bumps, of course.
Jacobs admitted Fields looked somewhat overwhelmed at first as he adjusted to the Chiefs’ offense.
That is understandable.
Reid’s system is detailed, demanding and built around timing, motion, disguise and quarterback responsibility.
Even experienced players need time to settle in.
But Fields has reportedly grown stronger and stronger as OTAs have progressed.
That is exactly what Kansas City wanted to see.
🏆 For now, Fields looks like the clear frontrunner to back up Mahomes.
He has the experience.
He has the athletic ability.
He is improving within the offense.
And he appears much closer to game-ready than Nussmeier.
If the Chiefs need someone to step in early in the season, Fields is the obvious choice.
Nussmeier may have long-term upside, but he does not appear ready to handle that job yet.
💫 The Nussmeier news should not be treated as a disaster.
He fell in the draft for a reason, and the Chiefs likely knew he would need time.
His 2025 injuries may also have affected his mechanics and confidence as a passer.
Kansas City can afford to be patient with him.
The goal is not for Nussmeier to win the QB2 job immediately.
The goal is to develop him into something more polished over time.
In that sense, sitting behind Mahomes and Fields could be the best thing for him.
🔥 The Chiefs have always valued experience behind Mahomes.
They know how quickly a season can change if a quarterback gets hurt.
They know a backup must be calm, prepared and capable of keeping the offense functional.
Fields may not be perfect, but he has played meaningful NFL snaps and brings a dynamic rushing threat that few backups can match.
That gives him a major advantage.
✨ As minicamp begins, the picture is becoming clearer.
Garrett Nussmeier is a developmental project.
Chris Oladokun is depth.
Justin Fields is the frontrunner.
And Patrick Mahomes remains the centre of everything.
The Chiefs hope Mahomes is ready for Week 1.
But if he is not, Kansas City now appears to have a backup quarterback gaining confidence at exactly the right time.
