I just think many of you are putting too much stock in that 7.5M.
If Urbs told them, "I'll come coach you tomorrow if you fire Frost and eat that 7.5M" they'd do it in a heartbeat.
That's an extreme hypothetical of course, but it's demonstrative. If the right post-Frost situation presented itself today and they'd miss out if they chose to wait until after the buyout drops, then they wouldn't wait.
The 7.5M isn't dictating the timing. Figuring out the next steps, is what is dictating the timing.
