Brian Kelly is successful? At what?
He's had the Irish as a top 10 program for most of his tenure and regularly lands pretty good recruiting classes, despite having to deal with far stricter academic requirements.
They've sucked in playoff games--but have done fairly well in other bowls.
Never won a national championship, but he's delivered some big-time wins there and has the program in the national mix more years than not.
For the record though: I don't see Kelly being a great fit for LSU. He actually runs their more traditional offense (two TEs and a power running game has always been an LSU staple and it's what Kelly has relied on at ND), but just don't see him meshing well with the fans or the culture there. He's too much of a Midwestern guy for an SEC blueblood like LSU.
