But I get the benefit of looking up at the screen and seeing it on replay. It confirmed what I thought. It's difficult. You'd like to see those calls made. I'd love to see our quarterback get those calls."

Coming from a person who's been fined before, coming from a person who everybody's expecting a lot from, I'm still going.

CHARLOTTE,Wholesale MLB Jerseys, N.C. (AP) — Cam Newton got the phone call he wanted.
Newton criticized league officials after Carolina's 30-20 win over Arizona on Sunday, saying that he doesn't feel safe in the pocket because officials are treating him differently than other QBs in the league by not throwing flags when he takes an illegal hit.

"I don't think there's a person that can go through what I go through and keep their head, you know what I'm saying?" Newton said. "Hits to the head, that's one thing, but when you're not protected in the pocket, that's another thing. It became the story of my life ever since I came in (to the league). It's always, 'Oh, we missed that, I'm sorry.' That's bull c---."
Newton said he is tired of hearing officials tell him they missed a call,Cheap Yeezy Shoes Online.
The phone call came Tuesday, but it's unclear exactly what they discussed.
