IMO, participation trophies teach kids the wrong lesson. It teaches them that just showing up is enough to get an award. Yes, some of the kids work hard and don’t achieve anything special, and really, that’s how life is. Not everyone is special in everything they try, sometimes not in anything they try, and if we just give out awards like candy, where’s the incentive to find that one thing that the kid really might be good at?
And I think the idea of “giving back the Super Bowl ring” isn’t analogous at all. They were part of a championship team in a team sport. Yes, some of the players contribute a lot more than others, but all of them contribute, either by filling in when people are injured or need to rest, or on specialized offensive/defensive packages, or on special teams. Hell, even the third string quarterback, who often goes the whole season without a single game snap, is making contributions on the sideline and usually QBs the scout offense in practice. Giving them all a Super Bowl ring is no different than giving all the kids on the best team in little league a championship trophy, you were part of a championship team. You don’t deserve a trophy just for being part of a team that came in last place.
The point is, kids should be playing sports because they enjoy them, because it teaches them teamwork, discipline, and other skills. If a kid is only playing a sport because he’s going to get a participation trophy, then he probably shouldn’t be playing that sport. Sports are a great and fun way to learn a lot of valuable skills, but it’s not the only way and it’s not for everyone. Sure, be a little extra generous with awards for younger kids (eg, perhaps awarding the top two or three in rushing and not just the best), but if there’s nothing meaningful beyond participation to award them for, then don’t.
That all said, I do still think it makes him a jerk to take away a trophy once it’s been awarded. Yeah, maybe they didn’t earn it in his estimation, though, I guess if it’s for participation, they technically did. But rather than taking it away, use it as an opportunity to teach them about the values and humility that he thinks it misrepresents.
