USC's athletic department is terrible. They left Helton in limbo in 2019, so that he was completely unable to recruit and ended up with something like the #80 class, thereby making it virtually impossible for him to succeed moving forward. Then they decide to keep him after that (very belatedly). Now, they suddenly decide to fire him after 1 loss?
I don't really have an opinion one way or another on Helton; I just know that I wouldn't have much confidence in USC's athletic department if I were a coach.
