Using three different advanced stats, we came up with a formula to rank all 32 NFL starters at the halfway point.
The formula uses Football Outsiders' DYAR metric, Advanced Football Analytics' "win probability added" metric, and ESPN's total QBR metric. These three stats measure slightly different things, so weighting them evenly should give us a decent picture of the NFL quarterback pecking order.
There are some surprises (Carson Palmer!) and some not-so surprises (Peyton).
