A month after 49ers offensive coordinator Greg Roman drew criticism from general manager Trent Baalke’s daughter, Cassie, he’s taking shots someone actually employed by the 49ers: right tackle Anthony Davis.

Two days after Davis posted a controversial tweet about Roman, he didn’t back down Friday when asked about his coach by a group of reporters.

Davis said he met with Roman on Friday — a meeting inspired by his tweet — and said he respected Roman as a “person.” When asked if he respected Roman as a coach, Davis didn’t respond.

On Tuesday, Davis said, via Twitter, that Roman told him when he was 21: “You know we can get someone off the street to do what you do.”

Davis’ primary issue, however, appears to be with how the 49ers have tweaked their power-running offense this season. After leading the NFL in rushing attempts from 2011 to 2013, their 23rd-ranked attack ranks ninth in that category this season.

Davis implied that was the reason the 49ers (7-8) will miss the playoffs for the first time since 2010.

“We’re going home after this week,” he said. “Maybe we tried to trick them this year.”

Later, he added: “I don’t think it’s that complicated what we need to do. I’m a player, and I just know what we don’t need.”

Asked about Davis’ criticism of Roman, Jim Harbaugh termed it “misguided” but declined to comment further.

Davis is certainly the most outspoken, but he might not be the only member of the offensive line disenchanted with the shift in offensive philosophy. After a 13-10 loss to the Rams this season, left tackle Joe Staley said a lack of execution and “dumb schemes” were responsible.

On Friday, Staley suggested running back Frank Gore, who has 962 yards and is averaging 4.2 yards a carry, has been underutilized this season. Gore is averaging 15.3 carries this season. He averaged 17.3 in 2013.

“Stats are going to say he had a down year,” Staley said. “He’s been getting 10 touches. I think he’s better. He’s been running harder, more physical.”
