Postcard from Bengals camp

CINCINNATI -- Here are some quick thoughts from my first day at Bengals' camp, where 640 fans and myself endured the 91-degree heat Tuesday afternoon:

  • The first round of team drills went to the defense. The receivers couldn't get open. On one play, quarterback Andy Dalton just threw the ball in the ground after the pass rush got to him.

  • Dalton went on to throw two impressive passes later in practice. He dropped a 15-yard pass over a defender and right into the hands of A.J. Green on the right sideline. He then hit Mohamed Sanu in stride down the left sideline after the rookie got past safety Robert Sands.

  • The two receivers who stood out Tuesday were rookie Marvin Jones and Andrew Hawkins. Jones got open a couple of times over the middle and then got free deep, but backup quarterback Bruce Gradkowski didn't see him.

  • There was a small scare toward the end of practice, when Pro Bowl defensive tackle Geno Atkins hobbled off the field. He got retaped and stayed to watch the rest of practice.

  • There was a brief scuffle that included backup guard Clint Boling. There's no truth to the rumor that Rex Ryan is coming down to scold the Bengals.

  • Cornerback Leon Hall wore a yellow jersey throughout practice, which signifies him as the defensive leader of the day. The Cincinnati beat reporters call it the "Tour de Zimmer" after defensive coordinator Mike Zimmer. It's kind of like a gold star that you wear. I would immediately give that yellow jersey to defensive end Carlos Dunlap, who was unblockable today.

I'm wrapping up my visit with the Bengals on Wednesday. My Camp Confidential piece on the team, which will have more in-depth observations, will run Friday.

Hope everyone enjoyed a very busy day on the AFC North blog.
