It is WWL (among other places), but the USC sites are also rolling with it as if it is true.
That means that since PC left for the NFL, they have cycled through his two of his Co-offensive Coordinators. I would assume that means that da Coach O is going to stick around as part of the package, unless Sarkisian takes Lupoi along with him.
What does that mean for ND? Sarkisian runs a more up-tempo style that Kiffen ever did. Although, recently, neither of U-dub's offense and defense has been all that spectacular.
So, is this Kiffen take two or a genuine movement forward for USC? I tend to lean towards the former.
