You know why Jack Morris is still in HOF discussion? Because won a shitload. Do you know why he won a shitload? Because he was good. Do you know how I know he was good? Because I saw him pitch.
Now, if I go back to university stats class circa 1988, I'll have some interesting bad luck like discussions with pencil necks, but sometimes you see what you see and you know what you know. Sometimes, stats are for figuring out the price of my car insurance and not who's a HOFer.
