Heading into 2015, there was one main concern surrounding the Cardinals: health.
But the offensive line has exceeded expectations, protecting Carson Palmer and paving the way for a ground game that is vastly improved from last season.
Palmer has turned back the clock, along with running mate Larry Fitzgerald, and the team seems to have found a gem in rookie David Johnson.

It's no wonder the Cardinals rank first in points per game (39.5) and 10th in total offense (363.5 yards per game).
If the offense continues to play at its current rate and Palmer stays healthy, don't be surprised to see Bruce Arians' club contend for the NFC West crown.
