McMath has a lot of physical potential. Not only is McMath tall (6'3) and big (225), he can also fly, with unofficial reports putting him in the 4.3s for a 40 yard dash. His size allows him to make contested catches over the middle, his speed allows him be a threat in the deep game, and his height makes him a huge red zone threat. The sky is the limit for McMath in terms of athletic ability.
Experience is where McMath lacks. In his junior year at LSU, he was stuck behind talent like Justin Jefferson, Jamarr Chase, Clyde Edwards-Helaire, and Thaddeus Moss. In 2020, he only played in six games, so again, there just wasn't a lot of time spent on the field. McMath's route running is where he needs the most work.
McMath is certainly worth a day 3 pick for any team looking for a developmental wide receiver. The bright side is that while McMath likely won't contribute immediately as a receiver, he has a lot of special teams experience, meaning he can be an impact player from day one. The biggest concern is McMath's lack of production. He was the sixth leading receiver last year on LSU (with 38 less receptions than fifth place) in a historically great offense. This year, he was still only the fifth leading receiver. While he played six games, he only logged 14 catches, which is concerning for someone who has so much physical ability on a team with no other stars on offense.
