Well if the roster has 23 players and there is only 10 spots on the field at a time. And you have all 23 players rated out at a high level. You could feel obligated to rotate them all in. Which could cause a break down in the slides and how the Attack work with each other. And its just really fun to get everyone all worked up and calling me names.
You ungrateful poster.....If the roster has 18, 23 or 35 players, the coach should feel "obligated" to get them all in. If 13 players are great and 10 players can't walk and chew gum at the same time, the coach should still feel "obligated" to get them all in. We should still be in a teaching mode for youth lacrosse, even at the AA level.
However, if you are the "National Champions" and all 23 players rate out at a super duper uber high level, how do they not know how to slide or work together, doesn't this team practice, doesn't this team have the most passionate, most intelligent, most caring, most intense, most benevolent coach and owner of all time. If these kids all rate out at a such a high level, you balance the units out(they are still better than everyone else) and dominate the world.
