1. DJax PI, questionable/bad call
You can't stiff arm to create seperation. It's a penalty, and was called. Blame DJax, not the refs.
2. the "phantom" holding call
It's holding if you get your arms outside your frame to hold back the defender. It was unmistakeble holding. Do people get away w/ it sometimes? Sure do. But that doesn't mean you should want them to make the wrong call.
3. the offsides defender on the phantom holding play
4. the SAME EXACT DEFENDER offsides on the next play (the sack)
I appeared to me that Hass was in a pattern w/ his snap counts, and they were getting jumped. If the defender is off on the count, he will appear offsides, because he's on the tackle when Hass gets the ball and can start moving. He wasn't off sides on either. Blame Hass for getting into a pattern, allowing the jump.
It was a TD. Nose of the ball broke the plane. I will say that it was inconclusive on replay. Whatever the call on the field was, it would stay. People are acting like he wasn't even close. On replay, it looks like the nose breaks the plane. That's a TD.
6. the fumble/catch ruled incomplete
He did catch the ball, and get two feet down, but he did NOT make a 'football move'. That's the rule. If it had been ruled a catch, and Pitt recovered, you'd be saying, "But, he didn't make a football move. It was no catch". They made the right call. Just because you don't like the outcome, doesn't make it a bad call.
7. the Hass chop block (that was a tackle)
Bad call. Horrendous call, and I don't know how they made it.
8. the non-calls on the Pitt line that were called on teh SEA line
There are non-calls in every game. There were more holding calls on Seattle that I saw that went uncalled. I saw the same on Pitts side. There is not a game, heck, there's not a series in a game, where you can't look in slo-mo and see holding. That's just the way the game is. Keep in mind though that Seattle only had 7 penalties for 70 yards. Take away the holding discussed here, the Hass 15 yarder, and the DJax 15 yarder, and we have 4 for 30. These are just the ones being discussed, but you're alluding to an avalanche of anti-Seattle calls. So, we have 4 for 30 yards. Pitt had 3 for 20. WEre the 'Hawks really getting a lot of line calls against them that Pitt wasn't? It's an empty argument.
9. the non-calls on Roeth for low tackles/blocks that were called on Hass (and Roeth was actually blocking one of the time, not tackling
I'll even give you this one. Are you talking about the Herndon return? What difference would it have made if he gets called for it? Didn't they get the Stevens TD on that drive?
