I'll be shocked if it doesn't happen, but I think Lyke has to be very careful here. Bryce Golden and Danya Kingsby have already tweeted their support of Stallings and their hope that he stays, and players within the program know Stallings is likely to be fired and are talking about leaving en masse (not Ellison and Wilson-Frame, obviously, who don't really have options). If Lyke is about to fire him, she's got to meet with the players before that happens and try to assure them that there's a plan, potentially a coach, and to trust her during the process before they make any hasty decisions. And I'm not even sure Lyke can have those meetings, at this point. It's spring break, and I was told the players were all heading home after they got back from NYC last night. So, a team meeting may not even be possible until next Monday.
I've always believed if Pitt fired Stallings, the risk was that they'd lose all recruits; several, if not all, of the promising freshmen; and Luther. And, of course, that would mean the new coach has to do what Stallings had to do last year and recruit 6+ new players in a recruiting window that's rapidly closing.
My belief has always been that it makes more sense to fire Stallings next year because it would allow the program to stabilize, and it would mean that this freshmen class would shake itself out more. We'd know who was REALLY worth keeping and who should be jettisoned. Plus, players would be far less likely to want to transfer two years in than as freshmen. At this point, a freshman can transfer, sit out a year, and still enjoy playing at his new school with new teammates for three years. Not so after next year.
I'd still be shocked at this point if the dismissal doesn't happen, but I actually think a bang-bang decision is not a good thing for the program.
