Baker Mayfield's NFL debut will go down in the history books as not only the first win for the Cleveland Browns in 635 days, but it also finds itself atop the leaderboard in terms of overall PFF grade in a rookie debut for an NFL quarterback.

His emergence detailed here, Mayfield lit up the field with his play, re-energized a fan base and brought the Browns back from a 14-0 hole. And did so in just over two quarters of play.

So this begs the question, where does Mayfield's strong debut rank among the all-time rookie quarterback debuts since PFF began grading every snap of every NFL game in 2006. Our research team hit the books and found some historic numbers for Mayfield.
