Presently, there are 6 active coaches on D1 with two 12-0 seasons, and Brian Kelly is one of them.
It pains me a bit to say this since I felt kelly should have been fired after 2016. But the truth is that he is a pretty good coach. I felt that he proved this in the off season of 2016 when he made all of his coaching changes, and it was reinforced in this past off season when he was part part of the decision to say "see ya" to Mike Elko when he looked for a bidding war for his services and then himself promoted Clark Lea to D coordinator.
Kely is not an elite top 3 coach imo, and we have not yet run the table on a remaining schedule that i think is a lot tougher than people realize with FSU coming on strong finally and USC being 19-0 at home under Helton (they are a different team at home), But, I think Kelly is a lot better head coach than a lot of the sour ND "fans" give him credit for being.
