This will never happen - minutes are meant to be difficult to manage.
difficult yes...impossible and completely out of my control?...i don't think so...
my starting PF is much better than my backup...so i understand that my coach would rely heavily on the starter...but my backup has better potential than my starter...and so i want my backup to get hours so he can eventually become better in the future...plus...don't want my starter getting too many hours...but i have no way to really tell my coach this...not that i know of at least...and so the hours my players are getting is out of my control...which when a game takes stuff out of your control (things that should be managable by you...it is a manager game after all) that makes the game less fun...
as for the 39 mins/game...yes...that may be accurate...and therefore if they played 2 games a week in the nba...then 78 minutes a week would be good...i don't deny this...i don't argue with this...what i'm saying is...the reason one only gets 39 minutes a game is because they'll get tired if they play more...they get pulled from a game so that they aren't dragging their feet on the court...but if a guy had the stamina to play 48 minutes a game every game...he would...and he wouldn't play worse in the following game because of it...he'd get a day off...have a rest...be fresh and ready to go next game...plain and simple...
