McMillan brought in his only reception (on three targets) for a 32-yard touchdown in the Buccaneers' 37-20 win over the Commanders on Sunday.
The rookie paid immediate dividends in his first game as a pro, and his day would have been even bigger had he and QB Baker Mayfield connected on a deep shot down the right sideline early in the first quarter. However, the duo made up for the misfire on the first play of the fourth quarter for McMillan's one and only reception of the lopsided win. McMillan did play a robust 50 snaps from scrimmage while last season's No. 3 wideout Trey Palmer was limited to 20, seemingly establishing the former as the clear top option behind starters Mike Evans and Chris Godwin heading into a Week 2 road showdown against the Lions.
