QBR gets a remake, and gets much better in the process. ESPN hired the guy (Advanced NFL Stats creator Brian Burke) whose work the original QBR was based on (EPA - expected points added). He has apparently been at work throwing out the clutch factor and the tilt toward the final result since he got there.

With three changes, ESPN's QBR has shifted more towards a stat to measure how good a QB is and away from QBQWinz http://www.footballperspective.com/e...ated-for-2015/ …
EDIT: Not sure how much Burke was involved here. ESPN is still using subjective measures to fiddle with QBR, for instance, they are now adjusting for pressure on the QB during the play.
