1/2 season + 1 playoff game does not make Tebow a good QB, and most certainly not to the level that you seem to be putting him on. Before you get on your knees for Tebow praising him however you want to praise him, let him play in the league for a few years. Stop being some blind homer over it.
With Tebow, the offense runs consistently below average with a few games where they click. Their defense has been keeping it close, and Tebow has been able to capitalize in close games. Keeping cool under pressure is a valuable asset that Tebow has.
Unfortunately, there is only so long you can ride a razor thin margin of error before things start to collapse. Baseball is the same way - watch teams that jump out to a good season start and check how they won. If they have a large amount of 1-run games, 9/10 you'll see them collapse as the season goes along. But every once in a while, a team has a magic season and keeps riding 1 run games (White Sox in 2005 year is one of them).
Now, the Broncos may have a magic season where everything goes right for them in the playoffs, but in the long run, close games tend to average out. Should the Broncos ride the Tebow-train as long as possible? Definitely. Will the Tebow-train keep running for several years? Although it's not impossible, I just don't believe it will.
Additionally, Air Yards per Attempt or whatever ass-backwards retarded stat you pulled up as magical proof is such a dumb stat. Sit back and actually look at it. Think about it. If there is any shred of sanity left, you'll realize how ridiculous it is. If you aren't careful, you'll turn into a baseball-esque nut that comes up with overly specific stats that really don't amount to anything. "Well, who is #1 in day games outside while wearing eyeblack playing on grass in temperatures above 70 and humidity levels at 60%-70%? TEBOW!"
