You've got to remember that 80% of the posters here are gigantic homers who will defend the coaching staff regardless of what happens. The fact that they completely turtled in the second half, took the ball out of Allen's hands, blew a chance to put the game away, then allowed YET ANOTHER long drive at the end of a playoff game is completely lost on them because the Bills happened to luck out and win.
You're right; it's probably not sustainable the deeper you get in the postseason.
