I agree with frustration, but I suspect this would make the GE too complicated. What happens if there's an injury or if a player fouls out? What about mid-game tactic changes (that allegedly happen). I think the suggestion speaks of the imperfection in the current system, but I don't think I've seen a really sound way to improve the controls on the way a coach allocated minutes during a game. Setting a weekly limit for players I think actually might not be the right way to do it, although if there were a way to make this limit only applicable to scrimmages... well then we might be on to something. I'm not sure if that's possible, though. Maybe we can get a smarter person than me to chime in on that? What's the harm in telling a coach that all players playing in a scrimmage cannot exceed a weekly limit of x minutes, and is that possible to implement?
I've thrown out the idea a couple of times for the option of having an "attitude" toward substitutions at each position:
1. Play to win! (coach plays starters exclusively except for when the backups are better due to fatigue, maybe even calls a TO to put starters back in after a rest).
2. Play as normal. (something like today, preferring starters but looking to get backups 10-15 minutes for example).
3. Rotate them! (trying to get both starter and backup to have as close to 24 minutes as possible, within the flow of the game).
I don't think any of those necessarily makes it easier to get a full 48 or to exactly manage GS. But I've always been disappointed by some of the situations I had early on where I had two guys of fairly even skill who both had pretty high stamina that I wanted to rotate, but it always came down to whoever started playing almost all the minutes and the backup playing few if there was no garbage time.
