On Friday, 49ers general manager Trent Baalke lamented the many good deeds of his players that go unreported.

That said, he also acknowledged their recent misdeeds are unacceptable.

The recent spate of off-the-field incidents involving the 49ers was a dominant topic during Baalke’s annual pre-draft meeting with the media. During the nearly hour-long session, Baalke repeatedly said he was “disappointed” in the actions of a few players who weren’t representative of the locker room.

“Those are damn good guys that work awfully hard at being good people and good football players,” Baalke said. “So respect that as well. Respect the masses because the masses are doing it right. And we’ll get the other things fixed.”

In the past three months, offensive lineman Daniel Kilgore (public intoxication), cornerback Chris Culliver (misdemeanor hit-and-run; felony possession of brass knuckles) and outside linebacker Aldon Smith (false bomb threat) have been arrested. In addition, quarterback Colin Kaepernick and wide receiver Quinton Patton are part of an ongoing Miami police investigation involving an incident with a 25-year-old woman at a hotel.

Kilgore has since had his charges dropped and can have the arrest expunged from his record. Kaepernick and Patton haven’t been accused of crimes and Jim Harbaugh, who decried what he viewed as the media’s rush to judgment, insisted there would be a “good resolution” to the investigation after hearing Kaepernick’s version of events.

Still, nine 49ers have been arrested or been the subject of a police investigation since January 2012. On Friday, Baalke said “one (incident) is too many.”

“There is concern,” Baalke said. “We hold ourselves to a high standard. The community deserves that. We represent the community. We don’t take that lightly. It’s important to us. (You) write a lot of things when guys do things out of character, which (you) should. I expect you to write on those. But I would also expect the same when our players our doing a lot of community service, are doing a lot of extra to be a standup part of this community. And our players work awfully hard at that. Awfully hard at that.”

Baalke was indirectly referencing players such as wide receiver Anquan Boldin, who was given the prestigious Byron “Whizzer” White award by the NFL Players Association in March for his community service. Boldin, whose foundation assists underprivileged children, was on a relief mission in Africa when he was traded to the 49ers last year.

In addition, other stars such as linebacker Patrick Willis and running back Frank Gore are pillars in what’s routinely described as a strong locker room.

Of course, that locker room also includes Smith, an All-Pro who has inspired countless headlines for his four run-ins with the law during his three-year career. On Friday, Baalke said the 49ers had no plans to sever ties with Smith, a blend of trouble and talent: Smith has averaged the most sacks per game of any player since sacks became an official stat in 1982.

In standing by Smith, the 49ers will fuel a perception they’ll compromise their standards if the player creating unwanted news off the field stars on it. On Friday, Baalke said the 49ers would continue to help Smith, who isn’t the only reason the team’s overall character has recently been called into question.

“Are we disappointed that we’ve had a string (of incidents)? Absolutely. Absolutely, we are,” Baalke said. “At the same time, very proud of the group of men that are in that locker room and what they stand for. On the field and off the field. Have a lot of trust in them. A lot of trust. I almost have as much trust in them as I have in my own family, my own children.”
