If you were at the chapin game, you would have seen that NW should have won that game by 3 or 4 goals. They only won 2-1 I know, but comparing scores really does not mean anything.
For example:
Argentina beats Venezuela 4-0
Venezuela beats Colombia 2-0
Colombia beats Boliva 2-0
Bolivia beats Argentina 6-1
If you look closely, those scores do not seem to add up. If Argentina beat Venezuela, who beat Colombia, who beat Bolivia, then that means Argentina should of easily taken care of Bolivia right? No, camparison of scores is not an accurate way to rate a teams talent, as these scores show. I understand that this may be the only means of comparison that you have, but it does not make it right. Put NW's or Irmo's talent, player for player, head to head against any other teams, and it would be a landslide. But just because you have talent does not guaruntee victory, as Argentina found out. NW did not play well against Chapin, but still got the win. As long as you get the W, the other stats do not matter unless you are comparing scores, which has been proven, time and time again, as an inaccurate way to predict how other teams would do against eachother.
