Allen showed clear improvement in 2019 vs 2018 in almost all areas - and the stats reflect that. As the season went on, he improved in terms of ball security, but did not improve enough in decision making and passing accuracy to spark the offense and rise to the "top 10" level. His overall completion percentage is near the bottom of the league, but you can argue that his TD to INT ratio, plus his running ability, puts him well above QBs with a higher comp % in terms of effectiveness. Still - he (and the offense) needs to improve further if the Bills are going to reach the Super Bowl or even remain consistent playoff contenders throughout his career. 58.8% is not good enough to win consistently in today's NFL, despite the playoff berth this season.
