7. Baker Mayfield
There’s no doubt Mayfield had a phenomenal rookie season. He joined a team that finished 0-16 the previous year, but instantly provided an injection of quality. Although was on the bench for the first few games, Mayfield soon made a difference when he became the Browns’ QB1.

A Heisman Trophy winner at the University of Oklahoma, Mayfield guided the Browns to a 6-7 record. He threw for 3,725 yards and 27 touchdowns as the starter. As a result, there were massive expectations on his shoulders before his second season, but he flopped.
