The reason Allen doesn't rank high in the PFF system is because he wasn't good throwing over 30 yards and he had too many turnovers. It is as simple as that. They have admitted that Allen was top 10 in the short to intermediate game according to their system. The problem with their system is that it weighs too heavily on big plays vs turnovers, the 2 areas Allen struggled the most. What they fail to recognize is that Allen's turnover problem isn't necessarily something that is not fixable. Jameis Winston throws a lot of interceptions every year because he makes bad decisions of every type and has never shown the ability to be something different. Allen on the other hand had most of his interceptions in the first half of the season and most of them were because he tried to play hero ball when the offense was struggling. Allen wasn't throwing interceptions because he didn't understand what the defense was doing, he threw them in spite of knowing exactly what was happening. That is why he was able to fix it and why the Allen of the second half of the season is more likely to be the player he will be. The second half of the season saw Allen fumbling too much but how much of that really defines what kind of QB Allen will be? Fumbles have a lot to do with luck and protection and even if it isn't, it can still be easily fixed. The point is, it is reasonable to expect that this will be the worst year for Allen in the number of turnovers, especially if the team around him continues to improve. The other area where Allen wasn't that good was in deep ball accuracy and there was a multitude of reasons for that but ultimately, for most QB's, deep ball accuracy isn't stable from year to year. Tom Brady would be the most notable great QB that has never been consistently good at throwing the deep ball. So the 2 things Allen was bad at this year are the 2 things that aren't stable from year to year (deep passing and turnovers). For those reasons, there is no reason to believe Allen won't be better next year and that's what frustrates me most about PFF; they have an expectation of Allen not getting any better than he was this year.
