The way I see it, you hold the players to extremely high standards... the QB should always make the correct read & throw, receivers should catch every ball, players should never make mistakes or else they don't deserve to win the game. You don't hold the refs to these same standards... they're being paid to do a job at the game just like the players (supposedly a fair, unbiased job), but you bash anyone that criticizes them or claims they contributed to a loss.
The way I saw the game yesterday was a tale of two halves... completely pro-Steelers by the refs in the 1st half (keeping it close) & then pretty fair in the 2nd half. The Cards dominated the stats in the 1st half, but something always kept them from cashing in for TDs (penalties, lack of penalties, TOs, drops, bad throws, poor decisions). The Cards played like crap in the 2nd half and let a 3rd string QB roll over them without getting any pressure on him at all. They did hold them to a few FG attempts, but their offense couldn't capitalize.
The 1 play I haven't seen anyone mention yet was the John Brown fumble... He's in the process of getting tackled & going to the ground when James Harrison dives into him helmet first & hits him with helmet-to-helmet contact & then clubs him with a forearm to the chin & knocks his helmet off. John Brown still is able to recover the ball until 6-7 Steelers pile on top of him & rip it away. In an interview, JB said he didn't even want to talk about all of the horrible things they did to him at the bottom of that pile. There are so many rules now about preventing hits to a players head... how is there no personal foul on this play? All turnovers are supposed to be reviewed automatically, but of course they're not allowed to apply a penalty they see on replay if they didn't flag it in the game (another BS rule that tells me the NFL doesn't give a crap about the integrity of the game or getting the call right if it affects the length of the game)
