But the Broncos' starting job belongs to the first-round pick. That won't change, barring injury, and the team is prepared to live with Bolles' ups and downs.
"There are going to be certain penalties. There are going to be holding penalties," Broncos offensive coordinator Mike McCoy said. "You think you've got a guy and all of a sudden the quarterback, like the other night, or a back or somebody bounces the ball outside. Those are going to happen, but there are some that we can cut down on and we just have to minimize the penalties. Not just him, but the entire offense."
The Broncos cited Bolles' "nastiness" as a reason why they picked him over Wisconsin's Ryan Ramczyk in the first round. But that nastiness led to penalties; that was a problem for Bolles at Utah and could be an issue for him at this level.
Still, he said he doesn't plan to change his style.
"I'm not going to stop playing my game," he said. "Things happen, but I'm never going to change the way I play. I'm never going to change the way I bring my energy. But, I do have a lot to work on. I'm going to fix those things, but I'm never going to change.
"If I change, then I'm not doing to be who I am. I'm here for a reason. I'm the player I am and I finish people and I come off the ball. That's why they brought me here."
--The ongoing competition at left guard appears to have brought out the best in third-year veteran Max Garcia.
Garcia, the 2016 starter at the position who moved back there after struggling at right guard in the offseason, began splitting repetitions with Allen Barbre last week after Barbre, a trade acquisition from the Eagles, got up to speed with the Broncos' scheme. But Garcia settled down and had a solid game last week against the 49ers.
"Max's pass (protection) has improved an awful lot," Broncos head coach Vance Joseph said.
While Garcia was stronger in pass protection, Barbre delivered in the running game. The first-team offense averaged 8.4 yards per carry when Barbre was in the lineup against the 49ers.
"It took him a while to kind of figure out what we were doing as far as our calls, but for about two weeks now, he's been very solid," Joseph said. "Both guys are playing well. It's going to be tight."
