The main thing I'm going to be watching for is whether or not SU is willing to spend the money to try to play big boy football. It should be fairly obvious between who they hire and what type of staff they fund putting together.
My main issue with hiring a defensive coach is that you'll likely have a rotating door at offensive coordinator, and likewise with the staff. Either they suck and you have to keep replacing them, or they have success and they're being hired away. Unless maybe they can find someone who's old, who is a good OC but failed as a head coach - then you have to pay them, though.
So it kind of circles back to, what are we doing here? Are we cashing checks to be the bottom feeder in the ACC and waiting on death row for the next round or two of realignment to off us, or are we spending and trying to compete?
