Its been reported that there is a ton of pressure on Lynn Swan to fire Helton. However USC has always wanted to make hires that have familiarity with the program. A lot of sources believe that boosters wanted Kliff as soon as he was fired and and as a compromise he was brought in as OC with the HC of the future role promised on the down low. It would be much easier to make him HC after a year or two in the Trojan family
It's amazing how certain coaches develop reputations that FAR exceed their accomplishments. KK was pretty much a failure at the one head coaching position he had. Yeah, talk about the offense all you want, but football isn't just offense. His teams always cratered late in the season and didn't play physical at all. I have a feeling if he looked like Gary Patterson noone would want him, and he certainly wouldn't be interviewing for NFL head coaching jobs.
Holgerson is another one I'd put on this list, but to a lesser extent. He has more skins on the wall and seems to be not quite so much in demand.
