Do you happen to recall his completion percentage or his QB rating?
His rating last season at Denver was about 73 percent. His completion rate was 46 percent. Here are Tebow's stats:

I agree with you that his completion percentage last season at Denver was not good. Someof the blame is his but there were a remarkable number of dropped passes and so many of the drops seemed to be on the receivers numbers 20-30 yards downfield that could have been real momentum boosters. Then there were the high number of QB hurries and sacks allowed by the Broncos' OL. Not only were the hurries and sacks high, they also happened quickly, often in 2 seconds, or less.
This season in Denver, Manning was also hurried in preseason and through the first 5 regular season games.
Sacked on average 3 times per first 5 regular season games, the Manning led Broncos went 2-3. With substantially all else being equal, the Manning led Broncos performed worse than the Tebow led Broncos of the previous season. Not until adjustments were made to the offensive line and possibly other offensive positions did the Broncos begin winning this season.
Going back to Tebow as a Bronco in 2011, as I pointed out in one of my posts, it wasn't as if Tebow was throwing wildly. When he missed (ignoring drops), it was usually because he was leading too far ahead of his receivers, or throwing at their feet which to me indicated that as he gained experience, he could bring the balls in closer to the receivers.
