With all the concussion hype the movie created and all the issues plaguing the league with protocol, I agree that he should be suspended and fined. I personally believe that a one game suspension is not enough.
“Beckham was penalized three times for unnecessary roughness, including a late helmet-to-helmet hit against a defenseless player in which Beckham left his feet prior to contact to spring forward and upward into his opponent, lowered his helmet and initiated forcible contact with his helmet, and forcibly struck the defenseless player’s head. This “blindside block” was particularly flagrant because Beckham, with a 10-yard running start, had an unobstructed path to his opponent, the position of the opponent was not impacted by any other player, and the contact with the head/neck was avoidable.” -Reported by Joseph Zucker
