I agree. Our federation did an exhaustive study of every player on half a dozen teams for an entire season and we noticed some players do like more minutes than others. Do you remember this famous quote from BB-Charles, "Players do have a hidden personality that you will discover as they play, and a part of this is that some players prefer more physical play than others. "
There has been endless speculation about the hidden physical play part but little about the other parts. I wonder if each players sweet spot for minutes is also part of their hidden personality.
