I am tired of people complaining about the running game in Sega's NFL2K for the Dreamcast. Gamers are saying it's too difficult to run on the computer and that the running game is almost non-existant. So you can see that running in the NFL is hard. It should be.
Defensive players are bigger and faster than ever.
The ability to close on the runner and fills holes increases with every season. The NFL is not like the high school ranks where running backs can easily dominate and rack up healthy 8 plus yard averages. In addition, if you check the NFL's web site you will find season stats. Through the first 5 weeks of the season, the top 30 rushers in the league averaged 3.86 yards per rush. If you take out the longest rush for each back, which definately skews the numbers, you are left with 3.51 yards per rushing attempt.
