An interesting, proposed new stats system for rating QB's. The passer rating we're familiar with was not a bad general statistic if one knew what it measured and how it measured it (unfortunately, many did not, leading them to either rely too heavily on passer rating or ignorantly reject it altogether), but given that it was just a summary of basic stats on a per-attempt basis, it could be pretty limited. This new rating system attempts to include more about a QB's play, but it can possibly get pretty subjective since one has to decide how to divide blame or credit on any given play.
And if Jay Cutler wasn't already viewed as an erratic QB already, apparently this new system makes him look worse.
