IMO the Offensive Line had their worst game of the season. Too many times the Cardinals were way behind the sticks due to Holding/Blocking penalties. Five offensive holding/blocking penalties to be exact. Those 10 yard penalties are absolute drive killers, on the road, in a hostile environment. Those take you out of your game plan and force you to throw the ball.
To be fair it wasn't entirely on the OL. Wilson and Rieman each had an offensive holding call against them and McBride had an illegal block. Still, I consider Rieman as a part of the line more than a TE as he is primarily a blocker.
The Cardinals have been one of the least penalized teams in the league this season. For them to continue to have success they need to eliminate these costly penalties that we saw in Seattle and the OL/TEs need to execute better as a whole.
