As far as Bledsoe being fourth in the NFC in QB Rating, that's a bit deceiving. He's actually second. You have to consider that Bulger didn't even throw 300 passes before being out for the season. He won't make the season ending minimum attempts qualifications. Brad Johnson hasn't even thrown 200 pass attempts yet. If he throws one interception, he'll fall five spots down the list.
Bledsoe is playing great, and doing it under pressure. If we could shore up his protection more in the offseason, the sky is the limit next year.
