Clemson is not what they have been and Harley is building something that can challenge the bully of the ACC.  We see it all around CFB,  Ohio St looks a little vulnerable this year ( they will be B1G champs this year I think), Oklahoma will get a challenge.   It’s not just prior bullies being knocked down a peg but who and how many might do it.  In the B1G we have PSU, Iowa, MSU and TTUN looking like they have made significant strides.  Heck even Rutgers and Maryland aren’t pushovers anymore.  Texas is showing signs of life and ISU has been knocking on door for a couple years in the Big 12.  SEC and PAC 12 look like status quo for most part but we will see how A&M plays Bama and how the Cocktail Party in Jacksonville play out in the next month or so. 
I think it’s great when the big boys have a little work to do before they get to the final four.  I might have some stressful afternoons in my chair and a lot of bathroom trips but i can’t think of a better time of year
