Kamaguruma's jersey number - 98
American Football Clinic Trivia Q & A of the episode:
Q: What kind of play is a sack?
A: It's when the quarterback is tackled before he can pass the ball. It stops the pass and can break up a big play. YA-HA!
Under certain conditions, Kamaguruma's bumping a reciever can be considered pass interference. It's legal if done within 5 yards of the line of scrimmage... more or less.
