Before the monkeys come to fling poo at me: THIS IS NOT A DISS ON WILSON.
First, Passer Rating and QBR are two different statistics. Stop referring to Passer rating or "qb rating" as QBR, because it's not the same thing.
Second, passer rating is a rubbish stat that rewards a certain style of QB more than others. A typical WCO dink-and-dunk passer is penalized by not having his average yards per pass be 12.5 or over. on the other hand, our offense is designed to suck in the defense with the run and then throw long passes over the top - something Wilson excels at because he can keep the play alive long enough for deep routes to develop, and throws a good long ball for the most part.
Because Wilson throws long and not as often as others, his TD per pass is very good. Because he waits on guys to get open, his TD/INT ratio is very good.
All of this lends itself very well to a very nice passer rating.
But that doesn't make passer rating a good stat. It's very limited and ignores some pretty major things, like sacks. This is not to cast any shade on Wilson - there are many other metrics by which Wilson excels as well as passer rating.
I guess passer rating is kind of like YPC for judging whether a running back is elite. Yes, it's a stat and measures a key part of his game, but takes no consideration of stuffs vs successful runs, how good a receiver out of the backfield he is, or a slew of other things that make some players special. It's like giving a guy who goes 0, 0, 0, 12 credit for his 4 YPC credit over a guy who goes 4, 4,3, 4 who averages 3.75 YPC but gets you first downs all the time and helps you to control the clock and the game.
