Some kids really want to be there and put 101% into playing the sport... out of my 4 boys, all of which have played sports... only 1 is the ESPN freak child... and he loves to play no matter the sport, the size of the kids... he loves it...
There is nothing worse than seeing the defeat in a childs eyes when they lose a game, especially when they know they had a chance of winning... same goes for the "equal playing time" rules imposed now in most sports, you have to play someone who doesn't come to practices as much as someone who does.... and how do you explain to a child that he has to sit on the sideline when he gives all he can, and watch someone else go in and play his position - and pick grass or stare into space... its not fair to the players who want to be there... it doesn't encorage the grass pickers any... all it does is hurt the kids who do give it all... I honestly think its terrible... what does that teach a child? In life if you don't try you'll get it all handed to you... and if you try your hardest... the other kid gets it anyway... just for showing up... that's not a good message either???????
If your kid doesn't want to play, don't force them, there are tons of other activities for them... if they do want to play - get out and help them get better so they can deserve the position they get on the feild... don't just expect them to play cause you showed up - teach them to work for it, and I'd bet they'd appreciate it all the more in the end!!!
