Linear,
I dont think it is fair to throw a blanket over all coaches.
Most of them are really good guys - in addition to being good coaches. Honest, hard working - and they have to make tough decisions every single year.
Yes - you will always find liars sprinkled about - but there is no way I would say they are even close to being in the majority - no less ALL coaches.
The trick for the parent - and the player - is to find out which ones are a bit slimy - and to stay far away from them.
IMO.
