"Patrick Mahomes: 82.22% (37-8) Lamar Jackson: 81.08% (30-7) Drew Brees: 78.95% (30-8) Tom Brady: 70.8% (34-14) Russell Wilson: 68.75% (33-15), Alex Smith 68.75% (11-5) Jimmy Garoppolo: 68% (17-8) Aaron Rodgers: 67.71% (32-15) Jared Goff: 65.96% (31-16) Mitch Trubisky: 65.79% (25-13) 19. Baker Mayfield: 51.11% (23-22)"
First things first, quarterback wins are the most overrated statistic. With that being said, I still felt the need to include it because of the length of the time period.
This list has a mix of guys like Patrick Mahomes, Drew Brees, and Tom Brady who are elite tier quarterbacks who played on great teams, and on the flip side quarterbacks who have good winning percentages because of the team around them, like Mitch Trubisky.
Baker finds himself one game above .500 so far in his career and considering all he has had to deal with so far, that is a pretty solid accomplishment. With how stacked the Cleveland Browns roster looks to be for the foreseeable future, he should skyrocket up this list in the next few years.
Just looking at this statistic though shows how important having elite quarterback play on a relatively cheap contract is for teams. The top two guys, Mahomes and Lamar Jackson have been playing on their rookie deals and have a winning percentage over 80 percent, with only Drew Brees, a future Hall of Famer, being close to that mark.
