1. Baker Mayfield
One of the most high-profile sophomore slumps in recent years, Mayfield revived the Browns when he broke onto the scene as a rookie. They thought that they had themselves a franchise quarterback and his first season backed that up. He threw for a record 27 touchdowns as he inspired the Browns to seven wins after zero the previous year.
But Mayfield took a step backward in 2019. He threw 21 interceptions as Cleveland regressed. Furthermore, his confidence came off as arrogance and he struggled in big games. Only time will tell whether or not he’s a one-hit-wonder or an elite talent.
