Plus that the Cowboys missed a PAT & an FG in regulation, although some of those penalties were questionable but those penalty calls were the same for both teams, Raiders had a bullshit false start call on the snapper for instance.
Well yes and no. Some were just bullshit calls. The last one on Brown was a joke, there was no contact that wasn't initiated by the receiver and Brown is not required to turn towards the ball, just not to impede the receiver's movement, which he did not do at any point.
The "holding" penalty that called back the touchdown was non-existant, it's a straight up block. If you're calling that holding, you should also be calling against the Raiders on every defensive play because Parsons was held all game without getting a single flag. Be good or bad with your calls but be consistant at least.
They also ruled a clear F-Fumble + recovery as an incomplete when it's clear that the receiver had the ball for two strides and made a game action with it in his possession before losing the ball.
The Parsons "roughing the passer" penalty, I mean, come on, there were some ridiculously bad penalties called here.
Raiders got 4 points (a TD turned into a FG), 5 first downs and field position for their game-winning FG off basically incorrect calls. I'm not claiming that the Cowboys played particuliarly well or that the refs were biased against them, but they did make a lot of bad calls (for both teams) and those that went against the Cowboys had a defining impact on the result.
The Raiders snapper penalty was stupid. I know the rules state you can't raise your heels, but he's the snapper, for god's sakes! Who calls those? It's actually a good yardstick of how bad the officiating team were.
