Errand you're discounting the fact that we were a month removed from our first playoff win in five years and Tebow took us to a ton of come from behind victories. At least in my case it was never a knock on Manning aside from his age and the perception that we were a few years away from being an elite D.
It's easy to be unemotional now but you're discounting the emotion at that time. My vote for Tebow was more about "why I root for sports teams" than it was about who would actually be the better QB. It was a conflicted time.
Now, the choice is clear.
