Cardinals' Jeff King confident in upside of offensive line

Of all of the issues the Arizona Cardinals had in 2012, none may have been more glaring than the issues along the offensive line. Still, despite those woes, at least one Cardinal thinks Arizona's offensive line may not have to go far to become a solid unit.

Arizona tight end Jeff King said the Cardinals offensive line isn't as far off as some may think. He cited the late season play of rookies Nate Potter and Bobby Massie as two reasons to be optimistic. Both Potter and Massie gained experience this year and progressed as the season went along.

"I don't think our offensive line is as far off as people think with the emergence of Nate Potter and Bobby Massie," King said, via Arizona Sports.

King compared Potter to Carolina Pro Bowl left tackle Jordan Gross. He said both are technicians and while Potter has a lot of growing to do, he has plenty of potential. As for Massie, King said his improvement late in the season was significant and he will only continue to get better.

As a result, King said he doesn't think the Cardinals need to target an offensive lineman early on in the NFL Draft. Instead, he said based on the improvement he saw throughout the season, the Cardinals may already have what they need.
