The defense is carrying him
The criticism has been that the contributions of the teams around him have been overlooked (that includes the defense, but also guys like Matt Prater, who's been phenomenal all season). Yesterday's game was a textbook case demonstrating how this was valid -- the rest of the team had a somewhat quite game, and Tebow fizzled down the stretch.
His success is unsustainable
Time will tell. Six game is not sustained success.
He has a bad throwing motion
The criticism has been that he has horrible accuracy, not horrible throwing motion. The criticism is very obviously true.
He's a good football player, but not QB (that one doesn't even make sense. It's a little like saying Obama is a good politician, but a bad president)
Obama _is_ a good politician and a mediocre president. To be precise, he gathered a ton of media attention, and got people to vote for him, but when it came to actually governing the country, his supposed revolutionary approach didn't quite work.
Glad you brought this up, I think there is a lot of similarity to the Tebow situation.
He pushes his religion in people's faces
He does. When journalists (according to folks like you) shove their microphones in his face, they actually want and expect to talk about football, so that "argument" is completely bogus.
They play the same position.
They both win
They both win in dramatic fashion
One is very outwardly Christian.
It's fashionable to bash one and make not very funny SNL skits about him.
It's not so fashionable to say the same exact things about the other.
No, it's fashionable to bash Tebow, because he's a media sensation, an unproven young player with questionable skills. It's anyone's guess how popular he would have been if it wasn't for his religious antics (my guess is: not as much).
Tebow stringed together several wins (against putrid teams, btw, combined win percentage of .440). Good for him, but that's about it. I swear, this is worse than the LeBron media love fest.
What's more funny is when they try to compare Cam Newton to Tim and Skip says "Oh come on. Cam is 2-6. That's an insult to Tim". That's a little more apples and oranges, but still.
What is funny is that Arizona won 6 of their last 7, but you won't hear about it, because their QB is not a sexy media pick.
