 * In the animation, the special teams are represented as field operatives with Sam Fisher's signature night vision trifocal goggles from the stealth action-adventure video game series Tom Clancy's Splinter Cell.
 * When Mark suggests a strategy of players using their combined force to launch their teammates, Tyler contests his idea, noting that it is against the rules of American football. In the animation, this is represented with a giant book titled "Da Rules" dropping onto the playing field and blocking the path of an already airborne player. The book is a reference a rule book of the same name from the American animated television series The Fairly OddParents.
 * When Tyler mentions a halfback, one of Mark's interpretations is a set of two players merging into a halfback, then the two halfbacks merging together to form a single "fullback". In the animation, this is represented by the players striking a fusion dance pose, which is a prominent technique featured in the Japanese media franchise Dragon Ball.
 * Additionally, Mark rates the "fullback" player as a super rare Shiny Pokémon and notes that the NFL trades players similarly to how Pokémon fans trade their collectible cards.
