The only numbers that really count are wins and losses.
That is the most abused stat ever. Wins and losses are pure TEAM stats. I hate it when QB's are credited with them. Head coaches, OK. They have a big role in both sides of the ball. Honestly, W-L's should be used to judge HC's and GM's and nothing more. I have yet to see a QB throw a hail mary to himself for a game winning TD.
