I don't think that's necessarily true. Its only 2/3rds of the way through the season. EDH is the favorite right now and should be able to win it, but any team has the opportunity to win a close game. Especially with agile managing and if any team out there has a little extra cash to pad their roster, EDH could be upset. Eagles get a solid inside player they could conceivably compete. Same with the Sheep Pimps. Donkey, you just need an outside scorer and you're right in there too. Heck, The Lumberjacks could even upset them with the proper enthusiasm and some outside firepower.
Of course its easier for EDH with each team that flops and drops the season as another loss, because it gives him no competition, but whats the point of this game? To sit around season after season waiting for the opportune time, or 'your turn' to win the league? No, its to be competitive and win. Has March Madness and the NBA playoffs not inspired anyone who loves Basketball or BB? Seriously, Haha.
