When a coach is let go, especially in the middle of a season, the sports section and the airwaves are filled with all kinds of crap denigrating them for all kinds of things, some of it not on the playing field. I can remember when Brewster was fired there was all kinds of talk about an impending staff insurrection, how he and Maturi were oil and water, how the team (almost in its entirety) was totally disinterested in academics. Some of it was likely true, but the press amplifies a whisper into a primal scream. There was nothing as lurid surrounding Brewster's departure when compared to Frost's, but I take a lot of this with a grain of salt.
I think Frost is a dolt and should be embarrassed that he ever took a paycheck with the University of Nebraska on the top, but we are seeing some classic piling on as he leaves town. If some of this stuff is true and violates the law, call the Lancaster County Attorney.
