On reddit, someone posted the Vikings offensive PFF grades from the Bears loss. McCarthy didn't make the bottom 5, which surprised me. PFF is putting more blame on his receivers than I think is right - I think if it hits the receivers' hands and then incomplete, they rule it a drop, but I'm not sure. But they put 5 drops on the receivers and said McCarthy's adjusted completion percent was 70%. Take that for whatever you think it's worth. I don't love PFF and I think McCarthy should be bottom five. Addison and Hockinson both had some big drops but that happens all the time. Right now, the offense can't keep a drive going if a receiver drops a ball or we have a pre-snap penalty. Good QBs can overcome that. Right now, McCarthy can't. Hopefully he will, and soon.
But a positive from PFF is that McCarthy got the ball out fast - his average time to throw was under 2.7 seconds. So that shows (arguably) that he is reading defenses better and making the right reads. Now he just needs to complete the passes.
