Yes, perhaps setting lines based simply on the overall ratings, but not taking into account placing left handers on the left wing, or placing grinders in the 3rd or 4th lines, and those sorts of strategies. We don't want the game to run itself, then it's just a simulation that we don't even participate in. Assistant ratings could improve the accuracy of the number we see as ratings of the players. So the real ratings for Skating, Shooting, Defense, etc could be masked, and a better assistant would make them more accurate. Not sure what 'tolerance' should be applied, but I trust we wouldn't see an actual 75 rating as a 50, even with a poor assistant.
