Point (a) Kiffin won't get a better offer this year IMO. I don't think he'll get a sniff from USC Senior. They have been there, done that, and it was hardly an amicable parting. LSU is up to it's eyeballs in Oregen's sleaze (he apparently hit on the pregnant wife of a high ranking University official!, among many other sketchy items). The last thing they want is Joey Freshwater. (Then again, it IS LSU, maybe they don't care, but I think they have to more selective than ole Joey!).
Point(b) Kiffin loves the idea of having Arch Manning. Have you seen him brag on Matt Corrall? Constantly builds him up, says he's the difference maker, etc. Kiffin is almost literally drooling at the prospect of Arch. He gets not only the no. 1 QB recruit, but on some lists no. 1 player, at the place that had Archie and Eli, and with all the attention the Manning name brings. Kiffin wants this very badly.
So yeah, he's gonna stick around until Arch makes his decision. But that's likely less than a year away.
In the meantime, IMO neither LSU nor Senior is an option for Lane, so not sure what other "high profile" job he would want this year.
I will say this though...if it's anywhere, it will be LSU, just because they seem to pride themselves on not having any standards. They let an obviously cheating bball coach stay a couple years ago, hired Ogeron who - was caught cheating at Senior AND Ole Miss (and UT from what I have heard, but maybe not caught), and had been convicted of domestic battery (or perhaps just charged). So maybe they don't care that Lane has been pond scum in the past. LSU has such low standards that maybe he can be a good fit there.
