Arizona Cardinals additions on offensive line will have them playing with fire

The Arizona Cardinals and Steve Keim set out on a mission in the 2013 offseason.

To fix the Arizona Cardinals offensive line.

He was close, but never quite reached that goal.

Now, with the signing of Justin Pugh, the Cardinals have made another attempt at fixing the offensive line. In creating a line that will allow the Cardinals to play out the model that Head Coach Steve Wilks wants to have in Arizona, a run first, grind it out, physical team.

Of course, signing Pugh along with Andre Smith, given the tenuous health of Mike Iupati and D.J. Humphries would be a big time roll of the dice. All have missed significant time with injuries: Iupati missed 15 games last year, Humphries missed 11 games last year and three games in 2016, Pugh missed eight games last year and five games in 2016 and Smith missed eight games last year and 12 games in 2016.

The names would all be an upgrade, Humphries, Iupati, Shipley/Boehm, Pugh, Smith would be as good as a run blocking offensive line as could ask for, but could they hold up?

This, like signing Sam Bradford, is a roll of the dice. Can Steve Keim nail this one?
