Larry Fitzgerald was walking on the sideline having just come off the field after scoring his third touchdown Sunday when he looked my way — I was down there, about 30 feet away — and yelled at me. I looked at him, and he yelled at me, "Working on my legacy."

It was a reference to his comment he made to me a couple of weeks ago, when I talked to him right before the season for (yes, shameless plug — so click here!) a story about him and his legacy. Since then, Fitz has played two games, leads the Cardinals in catches (14) and yards (199) and now touchdowns (3, all coming against the Bears, and one more than he had all of last season.) The trust is there between he and Carson Palmer. It took a while to make it click, and there were some injuries that got in the way, but this is the kind of production he was having last season in that happy place he and Palmer found post-shoulder/pre-ACL problems.

-- David Johnson is still a work in progress, but he looked excellent again Sunday, and not just because of the 108-yard kickoff return. His 13-yard touchdown run was nice as well, so patient before hitting the right hole. It's hard not to see Johnson getting much more work sooner rather than later, although Chris Johnson was fine (20 carries, 72 yards.) David Johnson, with 42 yards on five carries, just looks like a star waiting to happen.

-- Smokey Brown didn't have gaudy numbers — five catches for 45 yards — but he had two other plays that generated 80 yards in pass interference penalties. Both were near catches. Palmer slightly underthrew one, when Brown had Kyle Fuller beat. But Brown has gotten better at coming back through the defender even if the play won't be there, forcing the defender to interfere because he's not looking back at the ball.

-- The kings of efficiency: The Cardinals have made seven trips to the red zone this season. They have scored touchdowns on all seven.

-- The Cardinals did not allow a sack against the Bears Sunday, after not allowing one against the Saints in the season opener. Since sacks were made an official stat in 1982, it marks only the fourth time the Cardinals have gone at least two games without a sack. The last time was the final two games of the 2007 season.

-- Bruce Arians took the blame on the Palmer interception right before the half. It was an amazing play by linebacker Jared Allen, who leaped in the air on the quick wide receiver screen to bat the ball up and then pick it off.

"I got a little greedy," Arians said. "We wanted to put a nail in that one. I jinxed him. I told him the screen is going to be wide open. Do not let them tip it."

Allen tipped it. Arians said he called the same play for wide receiver Eric Moulds "32 years ago" and the same thing happened. "It was a flashback, 'Oh (expletive)."

-- An exhausted Frostee Rucker talked about the defense finding itself after a couple of leaky moments early. One couldn't be avoided, the veteran defensive end said — the zone-read runs of quarterback Jay Cutler, before Cutler got hurt.

"If Jay Cutler is going to keep the ball, you can't account for a guy like that," Rucker said. "You don't think the opposing team would risk getting their guy hurt. If those are going to be the plays to beat us, they're going to get that."

-- The Cardinals again averaged more than four yards a carry. The running game wasn't great, but it was enough.

-- There were no sacks on Palmer, but he was hit more than the Cards would want, including the flag-inducing low hit by Pernell McPhee that always gives everyone pause. But Palmer is going to have to absorb some of that. That's Arians' offense, and that's playing quarterback.
