RD.....70-63
WP... .552
WLS.... 89.5-62.5
WLC..... 8.29-6.71
WLA.....9-6

If Lidge had been Lights Out, the RD would have been 70-60 for a WP of .576 and a WLC of 8.65-6.35

His very presence strains the equation. A WP of .576 works out to 93 wins versus the 89.5

I think this shows that keeping Lidge around could cost us 3 to 4 wins. He simply has to go.
