Coach Bruce Arians loves to throw the ball deep, but with injuries to key linemen D.J. HumphriesMike Iupati and Alex Boone as well as speedsters John Brown and J.J. Nelson, it’s just not possible.

In the past, Palmer did seven-step drops with regularity, but this season, his dropback depth of 7.1 yards is the second-lowest in the NFL, half a yard shorter than league average, per Pro Football Focus. There’s no other option at this point, since he’s been pressured an NFL-high 75 times, per PFF, and has been sacked six times in each of the past two games.

Even run-first backs Chris Johnson(three catches, 31 yards) and Kerwynn Williams (one catch for 10 yards) got involved in the passing game.
