I can see your point, but I think this is a very poor idea. IF you do something like this, why not just allow an exact number of minutes per week per player so that there will never be any possibility that, God forbid, something might not be perfect for our teams. Come on, man, there are supposed to be pratfalls along the way. I had a guy get injured in the 4th minute of my game yesterday, meaning he only played for 24 minutes for the week. It happens.
I suppose if you are worried about guys getting too many minutes because of overtime in a scrimmage, leave them out.
Once I scored a basket that still makes me laugh.
