Arizona Cardinals comfortable with playing several offensive linemen; Cooper's camp, DJ's progress

If there is a position group that has Arizona Cardinals fans excited, it is the offensive line. With Jonathan Cooper healthy and the addition of Mike Iupati, there is a lot of optimism about what could be in 2015.

Head coach Bruce Arians told NFL Network, even now in the spring, "there are six, seven, eight players we're would be real comfortable playing right now."

I was curious as to whether first round pick D.J. Humphries is yet in the group. Arians said, "not yet, but he's close."

"He really had a good week last week," he said. "He settled down a little bit and knows how serious this is."

Looking at the group, the starting five would be in the group -- Jared Veldheer, Iupati, A.Q. Shipley, Cooper and Bobby Massie. Since he started last year, Ted Larsen would have to be in the group. Perhaps Earl Watford is also in there, as he has had a great camp. Bradley Sowell was a starter in 2013, so BA would probably be comfortable with him.

Shipley has been with the first team line all spring.

The big question is Cooper. Two year removed from being a top 10 draft pick and he has yet to make an impact on the field. He is healthy and looking good. "Coop has been outstanding," Arians told reporters. "I don't want to jinx him, but he's having a really good spring."

Previously, he has said it might be the best line he has coached.

Quarterback Carson Palmer is already impressed, saying he hopes Arians is right and then, more positively said, "I think he's right." He said the protection in the spring as been "fantastic." He recognizes there is a long way to go before we know how good it is, "but just looking at it, it's a good looking group walking out of the locker room on game day."

The Arizona Cardinals with a strong offensive line? That might be a first in 2015.
