May in fact be a good hire but his FSU defense was playing in the incredibly weak ACC. Let's see how he fares in a different league.
The main reason USC entered the SEC with basically just one rival (although I think for most schools this is normal) was because Carolina had spent 20 years as an independent. In this independent years, the Gamecocks played schools like Nebraska, Michigan, Florida State, Miami, Southern California, etc. But the independent schedule meant they didn't play many teams at all year after year after year to really develop a rivalry. In the SEC that is different. The UGA series is very important now as is UF and UT.So I would argue Carolina's major rival being Clempson is because of the 20 years as an independent more-so than record.
