INteresting analysis. Like Tim Graham I too can pull arbitrary numbers to prove my argument.
Rex Ryan - 126 regular season games, 61 wins, 65 losses, 6 playoff games, 4 wins, 2 losses (2 trips to postseason)
Bill Belichick - 128 regular season games, 61 wins, 67 losses, 5 playoff games, 4 wins, 1 loss (2 trips to postseason)
Flame away ya'll..
