I mean it would have to be bullshit anyway because no one would want a movie that's accurate about a greedy grifting asshole with a big mouth, so you might as well make Coach a fucking hero, the kind of guy who's running into a burning building during an artillery bombardment to save crying Ukrainian kids, coming out of the flames carrying them, while explosions go off in the backround from artillery, and the smoke swirls around him like Kurt Russel on Backdraft, you're gonna have to fudge the details, and it would be more fun, to me at least, to watch Coach doing all this heroic shit, while knowing how much of a faggot he is IRL, I think that would be part of what would make a Coach in Ukraine movie great.
