If it were my gig I would do as you suggest and get a few very tight-in shots from a high school football game. So tight in that it didn’t show faces, etc., and then I’d stylize the footage in After Effects and Illustrator using the trace edges livetrace function. I’d pull it down to B&W and then throw posterize time on it in AE to give it a strong cell animation feel — so it doesn’t have that gosh awful Charles Schwab commercial bogus animation 30fps look that gives me the creeps.
If you want to add color to the uniforms, simply use the new Photoshop Extended and use curves (and split handles using the option key” to drop out all the colors you don’t want and leave the ones you do — leave just one or two for effect) to colorize the frames you want.
You could also smear and trail the movement so that it plays up the action.
Add powerful underlay audio that punctuates the slamming and jamming of football.
No one will know where you got the footage or didn’t.
That’s what I would do. And if I wasn’t working on a magazine right now, I’d do you a tutorial so that you could see the steps in what I just described. (Hopefully, you are good enough with the tools I pointed to, to know what I am talking about.)
If you are good in the Adobe Suite, it will take you a day or two to do it all. Far less time than dealing with lawyers and clearances.
