Welcome to the new world of social media. Holly has lost the locker room and the players want a change and are playing their best hand to force it.
These players have good pedigrees; they know what's what when it comes to whether or not a coach is preparing them to succeed. think they are just justifiably tired of "taking the blame" which could in the end, help keep Holly on the job.
People have criticized these players for coming to the program because they presumably wanted a soft coach who wouldn't make demands on them but when they signal, "hey, we want to get better and win; find us someone who can do that"; then they are condemned for being disrespectful.
I say the heck with that. Desperate times call for desperate measures. They have been loyal soldiers but eventually sane people will mutiny against the general who keeps sending them out to be slaughtered.
