See, this is why you can't argue semantics with a lawyer.
Your definition of "good play/bad play" is not Dooley's definition of "good play/bad play". See, a good play for Dooley is one where:
Opposing player doesn't gain 20+ yards
Opposing player doesn't score
So we're doing good as long as we give up, say, 10 or fewer 20+ yard plays and 5 scores. 5 yard run? Good play! 8 yard run? Good play! 15 yard run! Bad play!
