Fvck your banners.
The idea that getting blown out on national television isn't embarrassing enough to make termination decisions, but that a banner or billboard truck will do it, is asinine.
At best, and historically at UM, banners have only played a (minimal) role in getting people fired. Banners have played no role in getting the right people hired. That's the logical disconnect. Fire the corch, new corch hired. Fire the AD, well, now you are getting closer to the root problem. But you are asking largely the same group of people (i.e., the BOT and doners) who hired Blake to hire a new AD. Good luck with that.
And as an alumni, The University of Miami will always be greater than the University of Miami football program. Even assuming a banner is good for the program (there is no evidence of that), it's a bad look for the University.
So, yeah, fvck your banners.
