For perspective, here are 2012 offensive line stats and points scored stats-- game by game. Some interesting alignments. The statistical case can be made that the Cardinals were already improving offensive line play significantly in the second half of the season.
However, statistical improvement in O-Line play did not translate to more points however.
Sacks Allowed Projection:
Actual Full Season Sacks: 58 -- 1st Most Allowed.
1st half of season projects to a full season of 78 sacks. Would have been an NFL Record.
2nd half of season projects to a full season of 38 sacks. Would have only been 13th most allowed in NFL.

2013 Projection: With aid through the draft via a 1st round OL pick, an increased focus on positional coaching, gained experience for 1st year players, movement to new, more natural playing positions and the return of Cardinals from injuries, I predict the offensive line to give up 30-35 sacks next year. I don't see that much of a decline from last season's 2nd half performance, even though I think there will be improved O-Line play. This is due to Arian's passing system which will put more pressure on the QB. Carson Palmer getting the ball out from behind the pocket quickly and into play will help.
