The fact is no "experts" including you expected Denver and Tebow to win the game. It was a great game, your arbitrary definition aside.
Actually I didn’t think the Steelers were going to win, too banged up. My definition isn’t arbitrary, it’s the standard 300 yards is a good performance, you don’t get to great until 400.
Meanwhile though even if all you say is true so what? One playoff win does not make a guy a good QB. Trent Dilfer won a freaking Super Bowl and spent the rest of his career a backup in bottom feeder teams. So even if we take as a given that Tebow’s playoff performance was the greatest QB performance since TV he’s still a QB with a 47.9 career completion percentage, no ability to read defenses, no consistency with his ball placement, whose success has come primarily by running a trick college offense. He got his chance, he did 4 training camps, had 4 coaches, nobody saw him as better than 3rd string talent. Time to accept reality, he’s a nice guy, but a crappy QB.
