College playoff expansion changes the game too. Kiffin can never beat Alabama, go 10-2 and make the playoffs most years for a cool $5-6M and be a king in Oxford.
Also, whether people choose to believe or not, Lane had a major religious conversion the last few years and has talked about much he has worked to mature (he quit drinking for example) and how important his support system is. Part of being sober (as I can attest too) is making sure you put yourself in the right situation. Taking in the Auburn job would not be that lol.
