More about Player Passing Completions Statistics
In the last few seasons there have been up to 6 quarterbacks with over 400 total completions in a season, which is more than what were season even towards the end of the last decade and for years before that. We’re subsequently seeing quarterbacks come closer and closer to averaging 30 completions per game. A decade or more ago, 30 completions in a single game was a noteworthy feat; now it seems inevitable that very soon a quarterback will average that over the course of an entire season.
