The Middle-Earth American Football Tournament

"Smaller" teams often have advantages at rushing

Not smaller "teams"- smaller running backs. And even the smaller college running backs that have success are considerably larger than a hobbit. And the offensive linemen that block for the running backs- they are most definitely larger than a hobbit. It would take at least four hobbits to block a large Numenorian, which means that the maximum number of men a team of hobbit blockers could stop is two, leaving the other nine men free to grab the little runt and drive him forcefully into the ground.

The hobbits had better be courteous to their opponents, or they might purposefully land on top of them when they tackle them. There'd be ribs breaking on every play.
