Enshrinement » 2012 Finalists comparative stats: Coaches - W-L-T
I just saw this on the HOF website and it illustrates my point about when Parcells had success.
His Giants Super Bowls were only when Bill B was his DC
He was 50% career with the Patriots and the only successful year was when Bill B left the Browns and was his DC.
He won 60% when Bill B was his DC with the Jets and barely over 50% when he was at the Cowboys.
The later years are really telling.
