It is that time of the week for us and we have a collection of mock draft projections for the Arizona Cardinals. This week, the four projections we have are all different. Cardinals fans should be pleased with pretty much all of the picks as they all fill a need on the team.

Let's get on with them. Hit the jump for more.

If you caught our own mock draft projections, we have Iowa OT Riley Rieff going at number 13 for the Cardinals.

SB Nation's projections also have an offensive lineman as the pick for the Cardinals, but instead, it is Stanford guard David DeCastro.

The Cardinals signed two offensive linemen in free agency, bringing back Levi Brown and adding Adam Snyder. Neither are very good. Drafting DeCastro gives them a blue chip protector who should be a yearly contender for the league's best guard.

Over at CBS Sports, Rob Rang has an interesting pick -- South Carolina OLB Melvin Ingram.

The Cardinals might believe they have the young players already in place at outside linebacker to successfully rush the quarterback with Sam Acho and O'Brien Schofield showing flashes in limited duty last year. For a club that has struggled consistently putting pressure on the quarterback, however, the opportunity to add another versatile pass rusher might make a lot of sense. Ingram is viewed as some as the top pass rusher in the 2012 draft class.

Rang's colleague Dane Brugler has the Cardinals drafting Stanford OT Jonathan Martin.

Of the four players, which would you prefer?
