I'm not seeing this.
When Tom Brady replaced Drew Bledsoe, Bill Belichik suddenly became a winner? Because before that, he was pretty much a loser.
What about when Jeremy Shockey broke his leg? Did Coughlin become a winner? I guess Kevin Gilbride became a winner, too.
Shannahan was a winner with Elway and Davis. Is he still a winner a decade later? What about Holmgren?
