SANTA CLARA -- Ahmad Brooks' coach and general manager refused to share their thoughts on the linebacker's alleged attack on a teammate last month, as 49ers training camp got under way this week. But on Wednesday one of the team's defensive leaders was quick to quell any distraction Brooks' incident with Lamar Divens might cause.
"He's tremendously sorry for what he did," safety Donte Whitner said of Brooks. "Anybody would be embarrassed. He's just going to have to move on and make the right choices from this point on. He'll be OK."
Santa Clara County prosecutors recently opted not to press charges against Brooks for a June 8 incident when Divens reported that Brooks repeatedly hit him in the face with a beer bottle after Divens drove Brooks home after a night of drinking.
"The bad choice he made outside of here, he's going to have to pay for that, and we don't know what it's going to be yet," Whitner said.
Coach Jim Harbaugh and general manager Trent Baalke have declined to state whether Brooks is facing any team-issued discipline in the way of a suspension or fine.
Brooks was not made available for comment.
The 49ers open the regular season Sept. 8 against the Green Bay Packers, then later face five other opponents coming off playoff appearances: the Seahawks (at Seattle on Sept. 15, at Candlestick on Dec. 8), the Colts (home, Sept. 22), the Texans (home, Oct. 6), the Redskins (away, Nov. 25) and the Falcons (home, Dec. 23).
"This is a demanding schedule. At the same time, we don't like it easy," Willis said. "When you have a tough schedule and you can win it, no one can take it away from you and say they had an easy schedule."
The 49ers' strength of schedule is tied for seventh toughest in the league, as their opponents carried a combined .520 winning percentage last season. The 49ers were at the other end of the spectrum a year ago, when they tied for the seventh-easiest schedule (.488).
Added running back Frank Gore: "We have one of the best divisions in football, and we like it like that. We like it tough. We know to get back (to the Super Bowl), we've got to do better this year."
"Anybody that says it's not a concern, they're probably lying," Whitner said of heading into a contract year. "It's always a concern, especially when you're in a business that's so physical. ... But I'm not in a position to make anybody do anything."
Among the players under contract in 2014 who could warrant an extension before then: quarterback Colin Kaepernick, linebacker Aldon Smith, guard Mike Iupati and wide receiver Michael Crabtree.
