[George1902]

Basketballs, soccer balls, and pucks (see 1999) have all been used in FRC games in the past. Perhaps we will see the return of one or all of these elements?

Never has an FRC game required robots to transfer scoring objects between them, probably because it's so difficult. In fact, instances where it has happened are remembered as epic (see the "A-bomb" of 2006 and 16's elegant assist 'bot of 2012).

FRC games have had robots cooperating using their drive trains (climbing obstacles, balancing bridges, climbing and lifting each other). This is a more realistic type of assisting and one that I expect to see.
