The irony is that when CC converted KYSR to the Alt format, the presumed internal expectations were not particularly high. The thinking went that if they could just take some marginal audience away from KROQ, they would cement their CC FM cluster over the CBS FM, cluster, at which they basically succeeded
Remember that KYSR started as an Alternative AC in the period of the mid-90's when there was a lot of fairly mellow alternative. That's where Seacrest landed in LA, and the station was a good fit in the early Clear Channel cluster.
