McMillan joined the Bucs in 2024 as a third-round pick, starting slow before eventually scoring six TDs in Weeks 14-18. The stage appeared set for bigger things in 2025, until the Bucs re-signed Mike Evans and Chris Godwin and drafted Emeka Egbuka. The first two ended up missing a lot of time, but not as much as McMillan, who suffered a neck injury in August and was out until Week 15. He then played around half of Tampa Bay's snaps in the final four games, putting up 2-38-0, 2-15-0, 7-114-0 and 1-11-0 (178 yards on 15 targets). Most of McMillan's teammates had poor efficiency numbers during that stretch, with Tampa Bay's offense curiously falling apart when it seemed to be getting healthier. In any case, Evans is gone now, potentially leaving McMillan and third-round pick Ted Hurst to compete for one top-three spot under new offensive coordinator Zac Robinson. There's no doubt Hurst is bigger and faster, but McMillan already has chemistry with QB Baker Mayfield.
