Kiper mock 1.0 reaction: Cardinals

There’s something to be said for the Arizona Cardinals drafting a kid whose nickname is Ironman.

In his first mock draft,Insider Mel Kiper Jr. has the Cardinals selecting Notre Dame left tackle Zack Martin, who set a school record with 52 straight starts in four years for the Fighting Irish. He’s 6-foot-4 and 308 pounds, and while some draftniks believe he isn’t tall enough to play left tackle, his strength and athleticism may combat his size.

Martin was the foundation of an offensive line that gave up just eight sacks, tied for second most in the country, playing against the likes of Michigan, Michigan State, Oklahoma and Stanford. His durability is intriguing for the Cardinals, especially since the offensive line has been hit with injuries during the past two seasons. The Cardinals need someone quick enough to redirect the likes of St. Louis' Robert Quinn or San Francisco's Justin Smith and Aldon Smith, or Seattle's Cliff Avril or Chris Clemons, just to name a few.

The Cardinals allowed 41 sacks last season, which ranks among the middle of the league pack.

Martin opted to return for his redshirt senior season and proved to NFL scouts that he got better with age. But his success in the NFL will depend on how well he can handle outside rushers at his height, when Arizona now employs a left tackle (Bradley Sowell) who’s 6-7, 315 and a right tackle (Eric Winston) who’s 6-7, 302.

If those three inches can come with fewer sacks, count coach Bruce Arians and general manager Steve Keim in.
