CFP: Should it be Saturday night or Monday night?

With the amount of commercials, replay reviews and other stoppages the game is probably going to run to 12:30AM EST.  

Should ESPN move the game to Saturday night and the tell the NFL to work around it? Laugh if you want, but having put up $7 billion for the CFP, I'm guessing that ESPN has the power to move it to whatever night they want.

ESPN would probably get a lot more mileage out of their pre-game coverage by having it Saturday instead of Sunday.  I know they're probably worried about fewer people staying home and watching on Saturday night, but I think it's just as likely that people aren't going to watch it on Monday because of how long the game is going to run.

Let me hear your arguments.
