I don't like Lane Kiffin either and here's why. First off his biggest claim to fame has been to be hired by Al Davis for another job which he was clearly not ready for. Talk all you want about what he had to work with. He knew that coming into the job and thought he could succeed, he didn't. Pete Carroll thought so little of him, that he wouldn't even trust him with the play-calling at USC. Sarkisian had to agree and Carroll retained veto power (which is not uncommon, but should be noted.) In addition, while USC had success with Kiffin as OC, they took a step back compared to what Norm Chow was doing prior to leaving who, speaking of, has never been very glowing when talking about the talents of his former WR coach. I admit even though some won't that the guy is a stellar recruiter. In fact, I think that and his pedigree is what got him the opportunities he has had. He is young, he has very little experience especially when compared to Mark Richt and Stoops when they were handed their respective teams so I think that comparison is ridiculous.
Also, and I know Al Davis is bat crazy, but the way Kiffin handled the whole deal with Oakland and the subsequent revelations by Davis has me real concerned about what kind of dude we would be hiring.
As some have said, there are risks with all of the current prospects for the job, I just feel that the risks with Kiffin are much greater.
