The first year that I participated in a Yahoo league with autodraft, I basically pre-ranked my preferred players according to their roster position. In other words, I filled out a game roster (1 QB, 2 RB, 3 WRs, Def, Kicker, etc.) with my top selections at each position.
DO NOT DO THIS!
What happened is that I drew the #10 spot in my draft and, of course, the first 9 players had also ranked the same QB, RBs, etc., that I did. So the first player on my list that was still available by the time #10 came around was the Defense--yes, my first draft pick was a freaking Defense. It was a horrible draft.
On the other hand, I finished 3rd in the league that year, but it was cause I spent an awful lot of time week to week making trades or working the waiver wire.
I guess I better start looking at player rankings and figuring things out this year! Good luck to everyone!
