Sounds like you're attempting to apply a little too much logic and analysis to find out where the team "really" is.
The team is 3-0. Its kind of that simple. Two teams face, and one team can get a win. Thats how it works. Its really that simple. So far, we've won all our games. I don't know how you can look really in-depth and extrapolate it. In the NFL any team can win any game. The advantage is slight, but it may go to a home team, or sometimes I give the odds in favor of the team with the better record, but a win is a win, and I like having 3 right now.
Its not a childish approach. Its the way allllll sports should be looked at. We're 3-0. No game has less bearing. We're 3-0.
