At this point, firing Kliff means losing Gibbs, which means another two or three years of lost defensive development and the potential to lose the only identity they have.
They aren’t good on defense this year, but if you look at the stats, they really have vastly improved over last season, and they’re returning 10 guys next year. If Duffey is able to sling it Tech-style next season and Gibbs continues to get the defense improving, they may have a legitimately good team.
Firing Kliff this Season not only exposes them to a busy coaching market full of better options, but also robs them of the chance for a good season next year.
The other side of this, of course, is that next year is probably his last shot. He has all the pieces to be successful ... so if he isn’t, then he’s out.
