Ok... IF anything happens with coaching changes, wouldn't that basically destroy our rep as being straight forward and honest with recruits? Seems like a pretty cheap thing to do, but maybe it's commonplace, I don't follow recruiting closely enough...
IMAGINING for the moment that this is true, it wouldn't, because recruits won't hear such announcements from the news the way fans do. Recruits will get the story from the coaches while the fans are completely clueless as to anything going on.
Again
IMAGINING, the reason you might want to wait until Signing Day to make things public is simple: to give all recruits the chance to hear it from official channels, before everyone and their mother on the internet start speculating about it and spreading rumor and false information. If another school can find anyway to paint our program as one in the midst of change or shakeup, they will use it. All things equal, it can change a recruit's mind. Sure you might argue it's ludicrous, but I'd argue it's arguable. And all it takes is changing one kid's mind, from the efforts of a coordinated bunch of men who are just good at this type of smear job type stuff.
