I don't think a Day 1 vote has very much in common at all with a Day 8 vote. Most Day 1 votes are cast with pretty weak reasons, and I'd wager that a Day 8 vote cast for Day 1 reasons would cause all sorts of eyeballing. Don't you agree?
A vote is a vote. And in particular if you're playing in a championship game, you better make damn sure you treat your votes like they matter. If I've said it once I've said it a million times, Day 1 votes get far too much disrespect. The game starts on Day 1. Throwaway votes, votes for no reason, etc, are inexcusable and especially so during a championship caliber game.
To continue your line of thought: A Day 8 vote for Day 1 reasons would indeed be weak. A Day 1 vote for a Day 8 reason on the other hand would be something I'd consider Championship worthy.
