Cut down on the interception and increase the touchdowns
He only managed to throw 17 touchdowns to the 13 interceptions he threw this season. He was far better in 2020 when he passed for 26 touchdowns and only eight picks. In the playoff games that year he threw four touchdowns to just one interception. Back it up to 2019 and he was more balanced at 22 touchdowns to 21 interceptions. In his rookie campaign, Mayfield went for 27 touchdowns to 14 picks.
The observation on all of this is that if Mayfield can pick up more touchdown throws and eliminate the mistakes and interceptions then he gives his team a much better chance at the win. I fully expect, especially the touchdown throws to increase a lot next season with the Browns considering drafting new wide receivers and finding a wide receiver or two through free agency.
