Sometimes you run into a team or have a game that goes awry and your opponent goes on to greatness. Since 2007, we've been the latter more than the former. When we've been on the receiving end - Florida '08, Clemson (once, I don't count the pick play year as dominance), auburn 2010 (why have Mark playing with one arm?), LSU 2019 (although I never understood how they called the WR in bounds after having stepped OO bounds unassisted ahead of that catch), a few more and then this year (inaccurate passing, turnover, their OL holding) - it's no fun and we rightfully default to "it's not them, it's us".
My parenthetical excuses above (my versions of "if Colt hadn't gotten hurt") are as pithy and off-base as those calling for a housecleaning.
A good thing about college football today is the bad thing about it today. A coach and an administration used to say it took four years for a new coach to get his players (for his system) into the team. Now, it only takes a year or, more charitably a full year and then the second portal. It only takes a year to lose them, too. It's the NFL with one-year contracts and immediate free agency. The dollars will speak, personnel evaluation becomes more acute, continuous retention efforts will vault, and directors of operations/player personnel salaries will close the gap on head coaches.
