Factual error: When Tony first goes to Johnnie's house a satellite dish can be seen mounted on the house in the background. Not in 1973. (00:57:00)
Continuity mistake: In the locker room scene after Tony injures his knee, Tony walks outside the room crying and he then throws his helmet against a wall, causing the chin strap to fall off onto the floor in front of the the doors. When the coach walks in through the door, the chin strap has disappeared. When the coach and Tony hug, look just behind the coach's right arm. You can see a quick glimpse of the chin strap back on the floor where it was before.
