I think that's probably one of the core things some of the non-sports people don't understand.....competitive sports are cutthroat, mean, brutal, and unforgiving. As much as we like the stories of the plucky underdog who overcame the odds, for every one of those there are countless on the opposite side where a person dedicated everything they had to playing at the top level, only to fail.
And I think what non-sports folks truly don't get is....that's one of the main things we love about it!
I played what used to be called Divisional basketball here. The best players in my team also played State league, a bunch of them were trying out or on the fringes, and then there were a few of us that were basically glorified rec league players.
My all around game wasn't up to it, and I was a bare 6 foot, but I had useful skills;
1) I turned up every night ready to play, and every training, and I did what the coach asked to the best of my ability. If he told me to play centre, I did it. (I mean...he was a better coach than that, but you know what I mean...lol)
2) I didn't complain when I got 2 mins (any game the state league players were available) and I went hard when I got 20 (any games they weren't available.
3) I was friends with the starting power forward, and was good at working with him, getting the ball in his spots, etc. We'd played a lot together, so it meant I could generate some offence off the bench, even though I was basically just a fast dude who could hit a wiiiiiiiiide open shot, and not much more.
4) The same starting power forward lost his license for drink driving, and I was able to pick him up for every training session, and every game, and make sure he got there.
I'm pretty sure point 4 on that list was actually my number one reason for making the team, although if I couldn't do 1-3 I wouldn't have made it anyway. But I was acutely aware that I was taking a spot a bunch of guys wanted, and I felt I kinda owed it to them to ball out to the best of my ability.
