Thats funny to see this post because that is my friends description of what he does.
He arrives at the game around an hour and half early or earlier. He likes to see the kids get off the bus and match sizes to the roster. He gets the punter distance and hang times, the kickers distances, holder and snapper. Watches routes of the QB and receivers to see how they run and if there are any hand signals being used. Offense and Defesive lineups. He talks to parents, especially mothers with "Spirit" pins. He said a mother will spill her guts about her kid and the team, injuries, eligibilities, team dynamic, etc, During the game he captures substitutions and follows the game flow. He did say sometimes the Hudl films the team gets cuts out certain plays and he tries to fill in what is missing.
I know he logged over 1000 miles traveling to and from games this year and sometimes he pays for the ticket but during conference play he has a pass. Never compensated for time, mileage, tickets or programs nor do I think he would take any money. He says, he is allowed to do what he does and loves the team he does it for and that I guess is reward enough.
