This defeatist attitude really seemed to take hold around when you joined the ATD, maybe a little before. Prior to then, "underdogs" went through the effort of showing how well they matched up against the opposing team, and sometimes would even win! Overpass was a 7th seed in ATD12 (the one before ATD2010, the first year we went with a yearly draft) and went to the divisional finals against the eventual champion (EagleBelfour). The next year, markrander was a rookie 7th seed who took out EagleBelfour in the 1st round because he vigorously pushed his team and actually was a real unfavorable matchup for EB's team.
So "underdogs" absolutely can win...if they match up well with the "favorite" and the GM actually puts forth effort.
I mean, I guess I can't blame people really... the ATD is supposed to be fun, and it can be frustrating knowing the other team is favored to win. Especially as the ATD has become more about "my line 1 is better than your line 1," etc, rather than how the teams actually match up against each other.
