It was 11 passes, but they were for a total of like 75 yards; also a number of those 75 yards were YAC. It's not like he was fitting balls into tight windows down the field. He was throwing screens/check-downs to Williams who ran for 10 yards, he was throwing slants to Rodgers (who at least once caught a pass that was low & behind him & ran for 10+ more yards). I get that a completion is a completion, but he wasn't able to make any big, clutch throws. And his slow start allowed the Pats to build a lead. The Pitt D held NE to a FG on the first drive, then forced a 3-and-out. Ben threw the 2 Pitt possessions away (again, the coaching/play-calling didn't help). You can't give possessions away against NE (or any good team). He couldn't get them into the endzone when it mattered (for the 2nd week in a row).He definitely had a slow start, but from there he went on to complete 11 or 12 passes in a row. That throw to Coates was on target and should have been a big gain early on. He had another great TD pass that was just flat out dropped by Hamilton, plus the TD pass where Hamilton just inexplicably ran out of bounds in the end zone before catching the ball. He wasn't great, but he wasn't awful by any stretch IMO.
I thought he played poorly, but even if you want to say he was average; average still isn't good enough in this big a game, especially when one of your other stars goes out.
