What if there were two teams that each just lined up 5 players with perfect levels of stamina, great levels of defense, and crap offense*? If they played each other twice in a week (so no form changes) and in the same arena both games (maybe one is a league game, one a friendly), do you (or we) think that they'd post the same team ratings? That the players would post the same player ratings?* These last two conditions so that fouls wouldn't be a problem - they could both play slow offense and defense to limit possessions and limit fouls that way too.
