Jay Cutler is off limits during practice, wearing a bright orange jersey, just like all the quarterbacks.
But the Bears defense seemed to annoy him on Tuesday.
Let's first establish that Cutler didn't have a bad day. During one stretch, Cutler completed seven passes in a row, including two to Johnny Knox and one to tight end Greg Olsen.
But that was in seven-on-seven drills, which means it doesn't include the defensive line.
When lines were on the field, the offense's unit certainly had some positive moments, giving Cutler time to complete passes. But there were a handful of clear sacks, as well, with defensive tackle Tommie Harris once swatting the ball out of Cutler's hands as he ran by in front of him.
Cutler showed the first sign of frustration, picking the ball up and tossing at Harris' feet about five feet away.
Later, though, the offensive line had two bad plays in a row in a full squad situation. Julius Peppers blew by Frank Omiyale. Then, the entire defensive line collapsed the pocket, and Mark Anderson appeared in position to get a sack of Cutler.
The quarterback responded by chucking the ball toward the right sideline, at the top of a large, white tent.
Asked if his quarterback was frustrated, Bears coach Lovie Smith said, "I don't know about frustrated.
"We have scholarship players on the other side of the ball too. Jay's a good player. I'm really pleased with what he's done. But it's good competition."
Peppers, meanwhile, downplayed any frustration the quarterback should have.
"I don't know if we frustrated him because he's not getting hit so he can't really feel it," Peppers said. "Yet. He wasn't taking any punishment."
Other notable things from today's practice:
* LB Brian Iwuh injured his knee during practice, and he was carted off.
* LB Hunter Hillenmeyer didn't practice because of a groin injury, Smith said.
* Cutler's best pass was in the middle of the field, to Rashied Davis. It appeared to be a forced pass, since Brian Urlacher and a safety were in the vicinity. But Davis ran right onto the ball, and he brought it in for about 20 yards.
* One of the more comical sights was seeing James Marten (6 foot 8) lined up at left guard. He's three inches taller than the left tackle on that play, Kevin Shaffer.
* Johnny Knox was definitely the most targeted receiver by Jay Cutler on Tuesday. He made several nice plays. But a sure touchdown was to Devin Aromashodu, who was streaking down the left sideline and ran under a deep pass from Cutler.
