re: If successful, is the O model sustainable?

Besides having to hire a new coordinator every couple of years, maybe even both of them, there is the additional problem of luring the very best out there to LSU. If we have the best already, then there is no where to go but down when we have to replace one of them. Who would be the equal right now of Dave Aranda? I dread losing him - maybe there will be some one just as good available when he leaves, but it's a risk.
