It is correct that drawing observations from a small sample size of 4-8 games may suggest some trends, but that sample size would not provide statistically meaningful conclusions.  What is more interesting in this discussion is the mention of the NFL and the NCAA, and the lessons they might provide. The NFL does everything it can to promote parity -- inverse draft order, salary cap, revenue sharing, inverse order scheduling, roster limits, etc.  With good management and a little luck, a team can go from worst to first in their division.  The NFL is by far the most popular, highest rated, and most financially successful of all professional leagues.  In the NCAA, the Big 10 and SEC are doing everything they can to separate themselves, financially and otherwise, from the rest of the FBS, i.e. the rich getting richer.  If they are successful, they will always attract the hard core fans, but when the casual fans who support Kennesaw St, Middle Tennessee St, South Alabama, etc. start to tune out because of lack of interest, the TV revenue will eventually dry up, and the big boys will be left with a big financial problem.  Maybe the "level playing field" that the NFL tries to promote is the better business model, and maybe the better model to follow in promoting high school football in Florida.  Or, hope that the "survival of the fittest" approach that some espouse will do the trick.  

I was actually surprised that some states have a mercy rule instead of running clock. 

Or I could throw these scores out at you: 38-24 42-17 38-10 27-17 39-31 41-21 31-14 Average point differential 17.4 points. And, yeah, you probably recognize these scores . . . they are indeed the scores of the first seven games of this years College Football Playoffs.   One single-digit point difference game  (the instant classic game between Texas and Arizona State).  Three of the games had a point differential of 20 or more.  And, in theory, these are games being played between the top 12 teams in all of college football.  Or I could throw out these scores: 34-7 48-21 43-8 31-9 These are all final Super Bowl scores from games played since 2001.  You know, that game played between the two best teams in the NFL.  Point is, point differential doesn't always tell the whole story, but I understand the argument being made that it is reflective of Florida high school football playoff games not being as competitive as most people would think they would or should be. 

I grew up in an era in which blowouts were common in Super Bowls. It never occured to me that such outcomes would be cause for calling for dumping the system! I think that as long as you have the best teams playing, it shouldn't matter what the margin of victory is. Of course, we live in a new era in which the Vice President, in running for the Presidency, has advocated for government engineering equivalent outcomes for all. It seems that the entire idea of having competitions, keeping score and crowning one team champion is antithetical to the pursuit of equal outcomes for all. It appears that this point has not been relaized by some.

Im surprised there is a mercy rule in championship games.  Seems like there should be no mercy rule if you made it that far and you might have the firepower to actually come back?
