Tetairoa McMillan is already coming off one of the best rookie seasons in Carolina Panthers history, but everything coming out of training camp shows that he may not be anywhere close to his ceiling yet.
McMillan caught 70 passes for 1,014 receiving yards and seven touchdowns in 17 games last season, becoming the first Panthers rookie to surpass 1,000 receiving yards. He won AP Offensive Rookie of the Year by a tremendous margin, receiving 41 of 50 first-place votes.
Calling 2026 a potential breakout doesn’t exactly feel right since McMillan already broke out. However, it looks like he may be in store for another leap.
Carolina Panthers are setting Tetairoa McMillan up for potential superstardom
McMillan doesn't need to suddenly become a completely different receiver to get to the next level. He simply needs to become a little more polished, a little more consistent, and a little more comfortable with the speed of the NFL.
He already has the production. Now he's getting another offseason to build on it. And there are already signs that the Panthers' offense is going to continue treating him like one of its most important pieces.
The biggest variable in McMillan's second campaign in the pros may not even be McMillan. It could be quarterback Bryce Young.
Imagine what McMillan's numbers could look like if the Panthers' passing game takes another step forward this year. Furthermore, there is greater familiarity now between the receiver and Young, and there should be more creativity with offensive coordinator Brad Idzik now calling plays.
McMillan has already played a full NFL season, and it was a pretty good one for the No. 8 overall selection in the 2025 NFL Draft. He knows what defensive backs are going to try to do to him. He knows the offense, and he knows Young. That experience matters.
So does the fact that McMillan appears to be embracing a larger leadership role within Carolina's receiver room. He told the Panthers that he believes the group is “very slept on” and also talked about the growing bond with Young.
Now it’s time to find out just how high that ceiling actually goes.
If Young improves, McMillan stays healthy, and the second-year receiver turns some of his rookie flashes into consistent dominance, a significantly bigger season is within reach. And he's bulked up considerably this offseason in pursuit of taking the next step into the elite conversation.
That is why this isn't really a breakout story. McMillan already broke out. This is about whether the Panthers have found the next great receiver in the middle of his arrival.
And if his training camp performance is any indication, McMillan's rookie season may eventually look less like a breakout and more like the beginning of something much bigger.
