I'm doing pretty well, but this year has been different, and it started early with the draft. Normally, I'm as likely to go RB with the first pick as QB, but this year I just didn't trust RBs as much, so I went QB first pick all the way, and all of my teams have either Rodgers, Brees, or Brady, and I think that's been the difference. The first pick should be the most reliable and productive guy you can get, and those guys have all been both.
This year I have 7 teams, 3 are 7-3 (2 in first place, 1 in second), 3 are 6-4 (all in third place), and the other is 5-5 (sixth place, injuries have hurt).
I've been playing on Yahoo since 2006, owned 25 teams and have won 8 championships in that time...3 of those last year...been to 7 other championship games. Of all my teams, only 4 have failed to make the playoffs.
