I dunno if there's a stat I trust for QBs. It seems impossible to divorce their statistical performance from scheme, personnel and *especially* game context. Pro Football Outsiders had him at a negative VOA and 25th in QBR last year, I guess. I'd say about 40%? He's got a chance if he's here and the new coaching staff is competent in ways that the last one wasn't, but he really looked like horsepoop a lot last year and defenses on our schedule really know how to confuse him and/or induce him into turnovers.
