As fans, we see them in game situations only. I think that a players initial ranking and playing time is based on what has happened in practice. Each practice is video taped and reviewed by the coaches. Statistics are also kept on all practices and scrimmages. These decisions are never based on somebodies feelings. Rankings and playing time are earned, not given out. If a player is earning it in practice, but it isn't showing through in games, then that is taken into consideration as well. The more game experience the coaches get with their new players, the more they can refine the rotations.
When wee see a player do some good things in a game, it makes us wonder why they are not getting more time. However, we are only seeing part of the equation. I have always liked to see everyone play. That may be one reason I watch practices as much as I do. The reason the coaches tighten up the rotation the way they do, is because they are trying to give the team the best possible chance of winning. I, absolutely, understand that thinking. :twocents:
