I know for certain they lost the game by kicking the field goal D:
C'mon Robert. They lost the game becasue they could not play defense in the final 3 minutes. Most so-called experts, sports radio talk show hosts, and reputable media personel all agree that Nolan did the right thing. Take the points and make them score a TD against a defense that had been playing well the last 3 1/2 weeks.
Plus, to many things could have gone wrong on 4th down. Remember how the 49ers almost cost themselves the win against Seattle a week earlier? I'm sure those memories played into Nolan's decision.
Next subject....Will Art Shell get fired after this season?
