Is there a stamina rating anywhere? So, I know how many minutes I should give my players.

I know that it shows the energy in the game, but that doesn't help me in setting my lineups pregame.

If you're simming your team's games, your players will be subbed out when their EN in a game reaches their "OUT" figure in the last column in the DEPTH CHART.

If your playing out your team's games, you can get a general sense of how fast EN's will fall by looking at your players' ATH rating in the RATINGS screen for your team. Generally players with lower ATH ratings will tire more quickly.
