Put him behind an “average” front line and he would literally be broken apart. The front line at Denver protected him better than any quarterback in a long time.
And even behind that line, Tebow put up a passer rating of 72.9 that year. Which would be good for 30th in the NFL right now.
The simple fact is, there is no NFL conspiracy against Tebow. The NFL is a pure meritocracy. If you can play, then you will be on the field, whoever you are or whatever you do off the field.
There was no strong part of those Broncos before Tebow united his Denver teammates. Yes, the defense was the first part of the team to show improvement.
