This cleared it up. Could not agree more UNLESS that person is like Winslow Jr. or something like that then I feel you can criticize the person.
I get that coach's are paid and leave etc. and yes there are exceptions like mark richt and randy shannon who are also alums, but I think coaches likewise give all they have to a university, most of them move their families and wives and children to be a part of it. No coach takes a job trying to fail but I do recognize the difference between a grown *** man making millions over kids playing a game.
But I actually fall on the other side of the coin when it comes to criticism. Both players and coaches are there to do a job, if they do not do that job, they are open for criticism (as you mentioned on their performance, not personal feelings). There are of course exceptions to any rule and one that comes to mind is Zion Nelson his TF year, he had no business being out there but the coaches kept putting him out there and in positions to fail (7 step play action slow developing plays). What is the kid going to say? No coach, I am not going in? I think most of his criticism should have been directed towards coaches. But overall agree with the premise of your post now that you cleared it up.
