The theory is if you get 21 first downs and 28 points you should always win the game.
vs GB 22 first downs 30 points = win
vs Det 24 first downs 27 points = win
vs Min 19 first downs 13 points = loss
vs Jets 26 first downs 34 points = win
vs Buf 29 first downs 45 points = win
I just find this stat interesting and plan to see if it holds true the entire season.
