I'll repeat my usual about BK: I like how he restored ND, continue to wish him the best...and hope he can evolve to be a better overall coach, as he still cannot win big games consistently. Even with all the resources available, more so than what he had at ND.
We can never know for sure the personal dynamics. But I sense BK lacks that inspirational charisma producing a whole > sum of the parts. And he doesn't get it right with game day play calling. He's gotten better in philosophy, a more balance O rather than pass happy gimmick stuff. But still not that top level elite coach who can win a NC.
If I were LSU, I'd give him 5 seasons. Even with great resources, well, see TAMU, FSU, USC, Florida, Tennessee. It isn't easy.
