Think she has two more years. The way I would play it as AD would be to see what happens once the season is over. If there is another mass exodus, it's time for the coach to go. Maybe if she loses Lednicky, also time to pack it up. I know everyone has said Lednicky isn't going anywhere but when you are that good, ambition will weigh heavily against sitting at the bottom of the SEC pool.
If the team stays intact, I think there is a solid foundation of players that can be built upon and I honestly would give Bird one more year. I don't know who we have committed or who we can pick up from the portal though. If new top talent isn't coming in, I'd go ahead and cut her loose as well.
That said, there was some perceived (or maybe firsthand) knowledge of the internal affairs of the program last year and if it really is bad because of the coach, hopefully the AD will make the right call.
