One of the criticisms of former Philadelphia Eagles coach Andy Reid was that Reid was overly reliant on his passing game. The proof is in the numbers.
Last season, the Eagles had 666 offensive plays that ended in a pass attempt or a sack (618 pass attempts, 48 sacks). At the same time, the Eagles only had 413 offensive plays that ended in a rush attempt. That means the Eagles were throwing about 62 percent of the time, which is way too high.
While part of that disparity is due to the fact that the Eagles were behind a lot last year, it's mostly due to Reid's fondness for passing the football, often at the expense of the running game.
Only time will tell if Chip Kelly is a successful NFL coach, but one thing that he has that Reid does not is a willingness to run the ball more frequently.
Through two preseason games, a similar computation shows that the Eagles are passing the ball at a much more reasonable rate, with only 56.7 percent of Eagles' plays ending in a pass attempt or sack. More running plays means more touches for McCoy, which means greater potential for McCoy to have a career season.
