Oh I totally agree with you. My point, which I just stated in another response, is that a QBs stats would improve simply by improving the talent around him.
Regarding your point about the supporting cast around Josh being exponentially better than it was last year, I'm not sure I agree. Perhaps because last year's cast was pretty weak. I love Brown but I'm not sure he's a #1 receiver, relative to other #1s in the league. He's certainly a very good #2. I think this O has a ton of potential. Overall, they are still below the NFL average in my opinion.
