You're right, it can be tricky...so can reading comp.Nope. Below 50% is not the definition of average. If every team in the league from top to bottom had a total of 112 wins (8 per team) before bowl games, then average would be 66.6%.
math can be a tricky thing. Just sayin.
The 49.999% clearly is about percentage of teams overall and not winning percentage. (Re) Using the example I gave above: Let's say you have 7 teams and you rank them 1-7. Team #4 would have three above and three below. So for this grouping team #4 is the average the three above...are well above the average and the 3 below are below the average.
Yes there are many ways calculate and define average and I just simplified it because the notion that calling the bottom teams in the East below average is actually correct but not an indication of the actual overall strength of division on a national basis...the better question is if they are closer to the 50th percentile or the 1st (nationally)...if it is the former than the East is pretty damn strong
So yes...math hard...numbers and stuff...especially for those who can't comprehend the concepts behind them
