It's too late. Once you Lock In the picks, it can't be undone. They can be locked in anytime, but no scores until they are.
I based my picks on the Spoilerish info mostly. The order changed a bit, after the first list, so part of my pool was gueswork, which is the norm! Right? I mean they don't always have all of it right. Well, except one time, several years ago (for All-Stars i think) we had a near perfect boot list! (who was that guy who used to do it?) Whoever, he knew his stuff. Anyway, that year, I think I came in first.
Thanks for the Spoilerish thread, puddin. I keep checking it! (for the other games).
