You don't release news on a Friday unless you want to sneak it in and have people forget about it.
Saturday are the conference championship games and with the CFP intrigue it'll get buried.
After the championship games we'll have the CFP announcements and then all of the angling and complaining about who's in and who's out.
If you don't do it today, the next day where the news will be really relevant will be mid next week which could be an eternity with this class hanging in the balance.
