Thanks for the feedback guys. It was really just a thought, something I may try in the future. I did have reservations about posting it here, but just wanted to see if anyone else had ever tried it.
billyho, As far as the elite teams, I also considered that and yes they would pose a problem because of their depth usually.
gillispie and rednu, you might have it best with the idea to try it at one to 2 positions or use it for situations
rednu, also, you are generally correct on the cpu wants your starter in, but I had multiple situations this past season where my best player/scorer/starter was taken out of the game for the last 6 minutes of the game although he was not very tired and his backup was on fairly fresh. In those games i lost by 2-5 points on scores that came in the last 30 seconds making me think if my damn scorer was in I would have own. My starter does not have bad stamina.
also gillespie, you are right in the sense of diminishing returns depending on the minutes your guys are getting, but in my case the starters with only one guy behind them usually play near the same minutes unless there is a major stamina difference.
