Yea Bortles isnt getting much love after this most recent game.  I feel as though all the stat geeks are banding together to defend his abysmally low QBR rating.  It's as if this is a personal affront against all advanced football statistics.  I still remember the week where Aaron Rodgers completed 50% of his passes and threw for only 70 yards with no TDs in a blowout loss and had a better QBR than Tom Brady who threw for 350+ with a much better comp% and 4 TDs to 0 INTs in a blowout win. I'm a math guy so I'm all for developing statistics to be used for real indepth analysis, but at some point those who keep producing the QBR statistic should realize it has major flaws.  And while I like what Pro Football Focus tries to accomplish and a lot of times I think they are "ballpark" correct, even their rankings are somewhat suspect.  It shouldnt even be classified as a quantifiable statistic or metric because it's completely subjective.  If two people can look at the same play and grade it completely differently, that isn't math.  That's like sticking your finger out the window and guessing the temperature.  If a second observer can't replicate the metric or the number, it is inherently flawed and subject to personal bias.  Heck forget a second observer, the same guy would probably grade the same game differently from one day to the next depending on his mood.  But in their defense, football is just a very difficult game to determine a worthwhile metric the way you can in baseball and to some degree basketball.
