No, SimLeague minutes are prorated to 82 games. So say a guy played 2460 minutes in real life. The number we use to compare to that 2460 is SimLeague mpg*82. So if he plays 300 minutes in his first 10 games then we would use 2460 (30 mpg times 82 games) as his SimLeague pace. So he would be right at his real life minutes so he wouldn't be fatigued.
In the playoffs, say he's played 2910 minutes in 97 games (82 regular season + 15 playoff games). He's obviously over his total real life minutes, but we would not use the 2910 number as his pace. We would still use 2460 (30 mpg times 82 games) as the pace number.
Hopefully that clarifies the prorating that we do.
