Well that was an annoying discovery.
I've got two QBs, who both play late games today. One of them has an injury, so I was stalling as long as possible before making a decision about whether to put the injured player in my lineup. Turns out, unlike my other league, ALL players are locked when the first Sunday game kicks off.
I'd like to suggest that we revisit this rule. It really is unfair when you have players in late games whose status is questionable. If they were playing early games, their teams would release information about them early enough to comply with our current deadline. But with late games, teams often wait until halftime of the early games to announce player status.
