For my family Christmas Eve has always been , well, Christmas Eve, not Christmas Eve Day. Are there really that many families that get together and hang out all day on Christmas Eve Day? That's what we do on Christmas Day.
That being said I think the NFL would have been wise to move the games to Saturday.
Speaking of the NFL and their scheduling, wtf is up with them scheduling a game at 5pm EST on Christmas Day? Are they unaware that many people enjoy a big Christmas dinner together? What was wrong with starting the game at 12-1 and then having the Monday nighter at 8? As it is I'm not going to get to see much of the early game.
