Underhill: Saints are interviewing probably 12 coaches (Tracker: officially 9 candidates) [Rapoport: Saints may add more]

I heard on the radio that the earliest the Saints could interview Aaron Glenn for a second time was on Monday January 20. Is that assuming a Lions loss, or can they still interview for a couple of days during the playoffs? I thought all contact was supposed to be stopped, but I may have misunderstood.
Only if they lose this weekend. If they make it to the conference championship game, the earliest will be the week before the superbowl.
