its easier to put a less skilled player on defense and teach them the ropes,this allows the coach to move a more skilled player up to concentrate on scoring.Alot of the freshman are club player that start out on defense,but move up to a different position as a soph.Then another fresh. will hopefully step into a starting defense position.At least thats how it works for our h.s. program.Plus everybody knows you dont get any respect when you play defense!!They do the dirty work and usually dont get the credit!!
