You have got to be kidding me. Yes screw it. Football pants are not meant to be clean. Some kids on my team didn't wash there pants all season. It was an honor to have nasty pants. So stop washing them. I think my mom just washed them once and that was that. The kids with real clean pants meant they never got to play, so it was kinda a pride thing.
In high school Kenny Stewart didn't wash his practice pants for about 6 weeks. They were so crusty with mud they could just about stand up with nobody in them. Finally Coach forced him to get them washed.
