Good point. There is literally no one that thinks Frost was a bad hire. There were literally million of people who thought Riley was a bad hire.
Sure, Pederhorst's minions were able to find and/or coerce some positive statements out of a few people, but there was a huge silent majority who said a mouthful with their silence, plus another good size portion of fans who called a spade a spade.
Riley was obviously never going to work out. Frost is obviously going to go down as one of the greatest coaches of all time.
