Historically the NFL releases some primetime games at the owners meetings in March. That obviously didn't happen this year.
News came trickling out that the NFL wanted to schedule all divisional games for week 17 so that's a possible reason for the delay.
History says today the full schedule will be released. In 2008, the schedule was released on Tuesday, April 15th. In 2009, it was released on Tuesday, April 14th.
Today is Tuesday, April 13th so you would think today would be the day but there's been no confirmation anywhere.
So, we'll keep waiting...
