With everything we know about recruiting rankings - do you really believe there is that much difference between a team with a roster that the average player rates an 83 and a team that rates 87? When you know a guy like Montez Sweat was rated a 3* 86? Or Benardrick McKinney or Darius Slay was an 82? Do you really believe that we are the only team that has players like that?
The reality is there really isn't that much difference in talent outside the Top 10 recruiters and say #75. Within that range other factors can make or break seasons very quickly because the margin is so thin. A rash of injuries; a player suspension; a coach screwing up a QB battle; or recruiting holes, can swing a team from being a 8 win team to a 5 win team quickly.
Look at our 2013 team - OL injuries and recruiting gaps kept a team with an NFL running back from being better than 6-6.
