British Prime Minister Benjamin Disraeli and plagiarized by Mark Twain: "There are three kinds of lies: lies, (danged) lies, and statistics."
Statistics provide a sort of comfort zone free of broad analysis and all the variables that can't be reduced to a number. They rarely tell the whole picture. For example, if Hoge doesn't get hurt, do we win the USU game (and change those stats in the process)?. And if he stays healthy, don't you think we win a couple of those other games that follow, again changing those stats? Does he improve from week to week, further changing those stats?
Or, another way to look at it, does Ty become a better OC if Hoge had stayed healthy?
As for autonomy for the HC at BYU - it'll never happen. It doesn't take place anywhere else on campus - why should it be different for Sitake?
