Not really. How many balls has Josh thrown away to avoid a sack? How many thrown away because the chance of INT too high? These are decisions he should be praised for, because last year he played "hero ball" and got blasted. Not to mention the high number of catchable drops by our undersized WRs.
No, the metric that matters - besides win-loss - is total TD v. INT. Scoring well in that metric wins games, and championships. Josh is rocking it right now.
