Agree but we don't know whether or not some selections are based on the identity of the whiners.
You are a coach *( congrats by the way) albeit of the younger brigade, but if you had someone questioning your decisions and talking out of school would you pick them? I am sure that you would be asking certain things of the boys, be at training on time etc.
Can't argue with you on selections, this all may be true and is forced to select a few players he doesn't want. But his positioning and rotations are all on him.
Nearly every year you get 1 or 2 little smart arses in my teams, you have to shut them down ASAP. One of my favourite ways if getting them in line is if any player mucks up at training, then we stop drills and the whole team does a lap. They learn quickly that yeah they are mates but mates don't like doing laps because of 1 player.
Also I have always been the strictest on my son and my best mates son, a bit of mind games, gets the boys thinking if I'm tough on my son, what will I do to them lol
I've also hooked a few boys for letting the team down in defence. Plus with coming late to training, in juniors it's obviously the parents fault so they way I got around that is whoever is constantly late, I would start them off the bench.
PS my best mate and I took over training of the U20s mid season, we got 5 out of 8 wins but it was too late and missed the finals. I have to say some U20s are worse than the U11s.
