You went from cutting kids is what you were suggesting to now a coach wanting kids to work out and not playing the kids that do, two totally different things.
The thing about sports participation is that in programs that win, the kids want to be part of the success. They are going to go that extra mile, summer workouts, going to camps to get on the field. At schools that are not winning and have little to no success in a sport like the DM metro schools, kids are not going to put in the time and effort without the reward at the end.
Its the same reason schools like BGM are playing 8 man when they could be playing 11 man, they can win more games in 8 man, get into the playoffs and maybe win a championship, which is never going to happen playing 11 man.
Oh, the school just needs to hire a coach to motivate the kids into coming out, that sounds great and easy, but kids today are not going listen. Hell most schools are struggling to hire a coach, and now we are going to hire coaching that are motivators also. Good luck with that.
