Roy Henry was a beast. The big thing to consider with regard to completion percentage and TD/INT ratio is that when Henry played receivers were fair game until the ball was in the air. Running routes in traffic was a death wish. There was no such thing as targeting or personal fouls for hitting defenseless players. Safeties and even corners at every level of play were head hunters. Also holding rules for offensive linemen were very different; things that are considered good blocking form today were holding then. Quarterbacks and receivers today could just as well be playing flag football.
