just more complex than other sports. My 10 year old's son played against a team two weeks ago that couldn't get a snap to the QB, couldn't execute a basic handoff, couldn't line up properly. My son's team won 58-0. I talked to one of their parents after. He said they'd only been practicing once a week. Now obviously, this was a B-team, but football just takes more organization and coaching, and understanding etc.
