In the triple lateral play near the end, Bill Hewitt throws the ball ahead of him as he's stumbling. Even in 1934, this was an illegal play.
On 4th and 3 with 30 seconds left in the game, Pete Smith says the ball is hiked to Carl Brumbaugh, who fakes a pass to Gene Ronzani and fakes another one to Harold 'Red' Grange. However, he actually faked handing off the ball, not passing it.
