he had one tipped ball against green bay which turned into a score
and he had one overturned pick against Arizona which was a terrible decision and pass, however the flag was thrown before he threw the ball FYI
He also had a TD called back against Washington because celek was tackled just shy of the marker and downed at the 1 yard line, and a throw to cooper where it was ruled down at the 1, but during the replay it showed cooper was clearly in, but chip decided not to challenge it
So with those 4 plays, he'd have 2 more TDs, and 2 more INTs, and one less TD, so overall 1 TD and 2 INT difference from his current stats, not a huge difference
basically the message here is QBs can get very lucky on some bad throws, and have bad luck such as ball bouncing from a receiver into a defender's hands.
in a 16 game season however, murphy's law balances out and the stats should be accurately displayed
