You guys are funny. QBR is just as relevant as the old school QB Rating statistic. Neither should be the end-all be-all statistic to quantify a quarterbacks performance, but it's a good supplement. And whats nice about QBR is it compares QB's performances against each other, which is a change of pace from the traditional version. Before, getting a 90 QBR was a barometer for a "good to very good" QB. These days 90 hardly means anything any more. QBR is just another form of doing the QB rating statistic, nothing more, nothing less.
According to traditional system he is 17th best, according to QBR he is 16th best.
You guys are pretty off base. Lots of things to **** on ESPN for, their QBR rating system is not one of them.
