There was a run on nobody at that position, and the Cardinals started one anyway for Maxwell Hairston, 47 picks ahead of schedule. It washes out to a C-, no better and no worse.
Leaving quarterback unaddressed is the roster risk they will have to answer for in the fall. The back end got a real overhaul.
If Maxwell Hairston and a couple of the gambles land, hindsight will be kinder than this grade.
