bounced back in 2020 after a down second season in the NFL, and, after two decades of scouring, it appears the finally have an intelligent, cohesive coaching staff and front office steering the ship in Cleveland.With the fate Camaron Cheeseman Jersey of the Browns firmly in Mayfield's hands, let's explore everything about his environment and what he needs to do to take another step as a quarterback.Previous installments in this young QB outlook project: , , , , , .These positive developments in a quarterback's game are noteworthy because they indicate the distinct po sibility of future growth. Here's a snippet of before the 2018 , and my pro comparison for him was :The Mayfield and Keenum stories are fascinating and extremely telling as to the current state of the NFL and the direction in which offenses are headed. Keenum had a ridiculously productive collegiate career in Houston's spread, pa s-happy, shotgun-only offense from 2007 to 2011. The 6-foot-1, 208-pounder exhibited decent athleticism and fine touch downfield. He consistently found open targets quickly and hit them accurately ... then went undrafted. At a similar size, with a similar collegiate career and similar strengths, Mayfield is likely to be selected in the top 10 -- or top 6 -- in the most-hyped quarterback cla s in 35 years. Mayfield has a stronger arm than Keenum, but the now signal-caller showed elite-level pocket drifting in 2017 during a career year in which he was one of the most efficient pa sers in football. Mayfield flashed pocket-drifting skills but does drop his eyes while under Tim Settle Jersey pre sure more often than you'd like from an early first-round selection.Mayfield finished with the in my season-long evaluation of all the plays of first- and second-year quarterbacks (out of 17 who played) in 2019. Mayfield never received an "A" grade all season but had just one "D+."In , I wrote this as a summary: "He should post better numbers than he did a season ago, yet, right now, I'm not predicting a true breakout season. One similar to -- and a bit better -- than his rookie campaign seems most likely." And that's e sentially what happened. I got a prediction right?!From his 2019 figures, Mayfield's completion percentage and touchdown rate improved in 2020 while his interception and sack rates dipped. Plus, he set a career-high 95.9 pa ser rating -- which is a tick higher than the league average of 93.6. Was he miles better in Year 3 than Year 2? Not nece sarily. But it was a season-long performance that gave the Browns more confidence in the quarterback position than they've had in a long time. Browns GM Andrew Berry has constructed a sturdy foundation around Mayfield, which was needed after a disappointing Year 2 for the No. 1 overall selection in 2018 draft. And the basis of that strong foundation is Cleveland's offensive line.For as much as I believe quality pa s-catching options are critical for young quarterback development, if the blocking is subpar, the efficiency of the pa sing offense is very likely to be suboptimal. There's a much stronger likelihood a team can field a respectable offense with an upper-level offensive line and average receivers than upper-level receivers but an average offensive line. Here's a telling statistic Sammis Reyes Jersey for more context on this theory of blocking importance -- in 2020, the league average pa ser rating was 103.7 from a clean pocket and 65.0 when the quarterback was pre sured. Ma sive disparity. And Cleveland's offensive line is elite. From left tackle to right tackle, it's basically the envy of the entire league.In the regular season, Mayfield was only pre sured on 26.4% of his snaps, the seventh-lowest rate in the league out of 39 qualified pa sers.At receiver, the Browns have good featured pieces in and Jr. has proven to be the reliable No. 3 everyone wants on their team. The tight-end trio of , , and is one of the deepest in the league. Rookie third-round pick adds a speed element alongside . Before I forget -- and are the best backfield tandem in football. Nice luxury to have.SchemeThe scheme in Cleveland run by head coach Kevin Stefanski is almost as vital as the blockers. Almost. Nothing is more critical than players in the .Stefanski operates a wide-zone based blocking scheme and, much like Sean McVay and Kyle Shanahan, he tries to make run/play-action plays look identical to the ground attack to keep the defense gue sing. He was integral in calming Mayfield in Year 3 by providing him defined Shaka Toney Jersey looks from clean or moving pockets. And play-action was a staple. Mayfield was one of 11 quarterbacks to have a play-action fake built into at least 30% of his drop backs last season.Mayfield, especially late in the season and into the playoffs, didn't have noticeable weakne ses as a pa ser. And at every level of the field, his statistics were slightly above league average.The "weakne s" for Mayfield isn't even his fault. He's just incredibly insulated in this offense. Here's the first line in Mayfield's report in on his 2020 season -- "Mayfield was the most protected quarterback in the league in terms of how many non-play-action, non-RPO, non-screen, non-rollout drop backs he had to make last year." His 67 designed rollouts were tied with Patrick Mahomes for the second-most in football, behind only .And all of it worked. The Browns finished with the 10th-highest . Stefanski's system has withstood the test of time. It can elevate quarterbacks. Cleveland is going to be one of the league's better offenses in 2021.The negative connotation surrounding the term "game-manager" has mostly gone by the wayside. But I still have a sliver of concern about Mayfield in a heavyweight bout with Patrick Mahomes and the or and the -- quarterbacks who certainly play Logan Thomas Jersey in awesome environments but themselves can boost those around them with regular demonstrations of supreme athleticism and arm talent. Can Mayfield do that in critical situations?Mayfield got comfy in Stefanski's scheme last season and operated it like a charm. He was also pinpoint accurate down the field, although that isn't a major element of the offense. His on-target rate was 52% on throws made 20 or more yards downfield. The league average was 42%.Beyond the deep touch, Mayfield's strengths were that he was "good" acro s the board. And in Stefanski's system, that's all that needs to be done for a team to move it efficiently down the field, particularly given the bulldozing nature of the offensive line and the presence of an elite feature back in Chubb and a dynamic backup in Hunt.The general takeaways from the "improving his weakne ses" and "strengthening his strengths" subheadings have created a conundrum. We know a (moderately talented) quarterback living completely inside the structure of a Shanahan-McVay-Stefanski system typically yields desired results. His team will win games. And based on the mini revitalization Mayfield had in 2020 in Stefanski's first season as coach in Cleveland, it's c
