Never fear...Pythagoras is here. From a piece on Expected Wins, as applied to the 2006 season...
G * PF² / (PF² + PA²) = Expected WinsFor the 2006 season:
G=Total Games; PF=Points For; PA=Points Against
13 * 403² / (403² + 310² ) = 8.17 Expected WinsActual Wins: 10. The blowouts skew things, but according to the Greek, we actually overperformed a little bit.
I'm sure you were all on pins and needles for months waiting for that one.
