Ya they can pick it, so long as it's before kickoff, or 5 mins before kickoff or something. Not sure when it locks that out.

But even if they pick thursday's game, you won't know they picked thursday's game until sunday at 1. but yahoo locks their pick in if they do.

it was a nice surprise last week when the picks were revealed on sunday and I saw 3 of the 10 ppl in my league picked Pittsburgh thus were out. I guess all they could hope for is that the remaining 7 of us all lost on sunday so we'd chop the prize pool.
