It depends on his ultimate goal.
If he wants to win a single national championship, just to have the ring and clout....he's more MUCH more likely to catch lightning in a bottle at LSU and get a ring (Miles, Coach O etc).
If he's trying to be on some Bobby Bowden, Eddie Robinson, Bear Bryant-ish, Ole Miss is better because they'll ride out 8 and 9 win seasons for the natty shot 2x or 3x per decade.
Problem with a coach like Lane is that he hasn't won shyt. It's like hiring Urban Meyer but if Meyer had zero rings. You get ego, swag, loudmouth bullshyt but there's no proof of concept with Kiffin. He's a hired gun because LSU thinks Kiffin gets them over the hump that Kelly couldn't. They'll be looking elsewhere in 3 years if they're not knocking on the door of a natty.
DeBoer's days at Bama are numbered after what we all saw yesterday. I don't think the school wants him.......but if he gets LSU turned around quickly enough......
