Re: Jeff Fisher: "Wha Happened??"
I've always held more value in what a football team does in terms of holding opponents below/above the other teams average.
A defense that consistently holds good offenses below their average and an offense that scores more/gains more yards than their opponents allow on average is a good barometer.
The OPS of football is yards per point however. It takes into account (according to the football stat heads I've talked to) everything like good offensive field position, turnovers etc. I'll dig up a link with a good discussion on it if anyones interested. This is a tool in the vegas handicappers tool box so if they like it, thats tells me it has some validity.
Ultimately for me, football just has such a small sample siz/short season and is so influenced by emotions that I give very little credence to the stats it generates.
