look for #12 in stripes, sometimes i'm the ref with the white hat and sometimes i'm some other position with the black hat.
i'm in the frame for all of that clip. i don't do anything but i'm still in there the whole time. i actually make a mistake by running away at the end of the clip, they're supposed to kick the convert next and my position is supposed to be 40 yards away from i actually ended up.
here i'm the Head Linesman so you see my head flash by as i try to cover these guys downfield. you shouldn't see me til very late in that clip and all i do is mark the spot where the play stops but i do it so very professionally.
here i'm back in the white hat again (that means i'm the ref) and i pretty much wave time in on the play and they score.
here i'm the umpire, which means i'm the fatman in the middle of the field (umpire is where all the old slow guys officiate). the run goes up the middle and i simply rotate and follow the play.
finally i'm the back umpire which means that i'm the deep guy. the rule for that position is just don't get beat deep because there's nobody else behind you to cover your butt if you make a mistake.
