I had some history with one of these terrible type of teams and it played out like one of those cheesy kids movies except we sure as hell didn't win the championship in the end.
I helped my son coach a 10 year old flag football team one season for some of his public service requirements in high school. We had never been involved with this league and because my son found out about the coaching vacancy late we missed the tryouts and league "draft". Thus, we ended up with all the kids none of the other teams wanted including a kid with autism and another kid who's parents signed him up to help "socialize" him. He wanted to be anywhere other than a football field.
The coach with the best team obviously loaded it up with the best players claiming that he had to have "best-player-so-and-so" on his team because he shared a ride with "other-best-player-so-and-so". And of course he had to have his son and his son's best friends who also happened to be good players etc., etc., etc.,. You know the kind of guy. Anyway, we sucked out loud. Couldn't run, throw or catch. The autistic kid, bless his heart, tried but just couldn't grasp the concepts of football and the other kid would spend practice in la-la land singing showtunes.
So when we played the stacked team with dooshbag coach they were predictably annihilating us. They were using trick plays even after they were winning by a half dozen touchdowns and dooshboy was acting like he was winning the Super Bowl. My kids were trying and weren't letting up even though we had no chance. By the 4th quarter it was a rout. So dooshboy decides he's going to be "magnanimous" and has his kids no even try to grab my kids' flags or even run after them. This of course embarrassed my kids to no end and pissed me the f**k off. I walked over to smirking dooshboy and quietly told him to cut that sh!t out and that if he does it again we will have sterner words later. He feigned righteous indignation but had his kids quit.
It's been 6-7 years, but when I see this guy around town I still stare him down.
