So let's start with 3000 yards, 60% completion average over 10 games straight, with poor OL play, ONE solid, consistent WR for the whole season (and even he missed 2 games), and he was coming off an off season of rehab.
Now he'll have an improved OL, even if only by a little, he should have a full WR corps to throw to rather than one guy on a consistent basis, he's one more season removed from injury and has spent a lot of time with guys who know how to help him, and we're playing an easier schedule...
Yet you pulled out of thin air that he will somehow drop to 50%... Seriously, 50%? Where in the world did you come up with that? You can't just pick random numbers and random comparisons to make and expect anyone who even half knows what they're talking about to agree with you. You don't have to be a football genius to call this one out.
