Believe it or not...Tomlin is currently 12th overall in coaching win % at 36-18 (0.667). That's ahead of #23 Belichick (153-93, 0.622), #26 Reid (112-70, 0.615), #32 Shanahan (150-101, 0.598), #35 Sean Payton (41-29, 0.592) and #36 Mike McCarthy (41-29, 0.592).
(This appears to count only regular season games...)
Granted, that's a small sample size for Tomlin, Payton, and McCarthy, but still.
A win versus the Saints jumps Tomlin ahead of Paul Brown and Tony fucking Dungy to #10, 0.673.
