Lamar Jackson is rated a 76 overall by EA Sports Madden 20. Is Jackson probably better than his rating suggests? Absolutely. He’s 6-1 as a starting quarterback and while he has a lot to work on, he got off to a strong start. It just doesn’t matter what his Madden 20 rating is.
One of the good things about the Madden ratings is they go up and down as the season goes along. If Jackson is better than a 76 overall in reality, the number will go up. Jackson has a long list of people to prove wrong so this won’t bother him in the slightest.
