Cleveland Browns quarterback Baker Mayfield was impressive during his rookie season and one stat released by Pro Football Focus shows just how well he has played. According to PFF, Mayfield had an adjusted completion percentage of 74 percent on third down in 2018, which was the seventh best in football.

According to Pro Football Focus's Mike Clay, the following formula is used to calculate adjusted completion percentage.

Adjusted Completion Percentage = (Completions + Drops) / (Pass Attempts – Spikes – Throwaways – Batted Balls – Balls disrupted by a QB hit)

Adjusted completion percentage is used to give a true look at how well a quarterback is performing while taking away the things that they can't control like spikes, drops, and throwaways.

True completion percentage is still important when evaluating a quarterback, but the best way to look at them might be the adjusted completion percentage.

Last season, Mayfield started 13 games throwing for 3,725 yards and 27 touchdowns while completing 63.8 percent of his throws. He did throw 14 interceptions and that is something that he needs to clean up going forward.

The question heading into this season is, how will Mayfield and the rest of the Browns react to the expectations that are on the team this season?

Mayfield and the Browns didn't have any expectations last season, so having the strong finish to the season was a plus. This season, the Browns are expected to have success and make the playoffs and some players rise to the occasion with pressure, and some players crumble. Which will it be for Mayfield?
