BEREA, Ohio -- Baker Mayfield has entered uncharted territory for Cleveland Browns quarterbacks.

Since Gregg Williams replaced Hue Jackson as head coach and Freddie Kitchens replaced Toddy Haley as offensive coordinator, Mayfield has had five games in which he completed at least 67 percent of his passes. No other Browns quarterback has accomplished that feat since 1999, the year the Browns returned from a three-year hiatus, according to ProFootballReference.com. Mayfield is also one of only 42 NFL quarterbacks to do that since 1999.

The most recent Browns quarterback to do this was Milt Plum in the 1959for passer rating in a game, with 151.2 against Atlanta, and he joined Aaron Rodgers and Kurt Warner as the only quarterbacks in NFL history to top 140 for passer rating in consecutive games (minimum 20 attempts).

Mayfield has 10 consecutive games with a touchdown pass, marking the first time a Browns quarterback has done that in a season since Bernie Kosar in 1987. Mayfield has a ways to go to catch Kosar, though; he had 17 between 1986 and ’87. Frank Ryan owns the Browns' all-time record, with 24 such games in a row (1965-67) and is one ahead of Mayfield with 11 in 1963 and ’64.
