The 49ers did three things on Friday:
▪ They signed safety Jaquiski Tartt to a contract extension.
▪ They had a news conference with their first-round draft pick, Mike McGlinchey, and showed him around the stadium and facility.
▪ They traded right tackle Trent Brown to New England.

Tartt is one of the team's "Monday guys," one of the players who always seems to be at the 49ers facility. He's a dedicated worker, a committed employee, a team player. When Reuben Foster had a court hearing in San Jose last month, Tartt and cornerback Richard Sherman showed up in support of their embattled teammate.
"We're thrilled to have extended him," general manager John Lynch said. "Jaquiski is a guy we feel really good about. We wanted to, when we came in, we wanted to reward our players who represent our core values and we think are really good football players and are fits in our scheme. We thought Jaquiski was one of those."
The 49ers, meanwhile, like McGlinchey for how he plays in the trenches but seem to really love him for how he comports himself off the field. He was a two-time team captain at Notre Dame. An anonymous scout told Packers reporter Bob McGinn that McGlinchey "acts like a CEO of a Fortune 500 company. He’s not a devastating left tackle but he gets his man every time.”
Lynch said McGlinchey had one of the two best interviews the 49ers conducted at this year's scouting combine. "… One of the smartest players in the draft, off the charts in terms of his presence," he said.
Then there's Brown.
How he came back from the shoulder surgery he had late last season always was going to serve as a litmus test for whether the 49ers would ink Brown, who is heading into the final year of his contract, to an extension. He and the rest of the 49ers reported for the start of the team's offseason program on April 16.
It was about that time that Lynch and Kyle Shanahan began zeroing in on McGlinchey as their first-round pick. Coincidence?
Brown's offseasons have been a bit sloppy. One spring, albeit before Lynch and Shanahan arrived, he barely could make it through the May and June non-contact practices. To his credit he got in far better shape for training camp that year, then in the regular season went on to be one of the best right tackles in the league, especially at pass protection.
Anyone wondering about Brown's future with the team may have picked up the hints.
The 49ers said that some players are able to play through labrum tears – linebacker Brock Coyle, who re-signed with the team in March, did just that in 2017 – but some cannot. Brown missed the last six games of the season with his injury.
The 49ers love it when players conduct their rehabilitation in Santa Clara. Brown did his in Florida. And he may not have been as devoted to it as the 49ers would have liked. "Trent’s a big man," Lynch said four days before trading Brown. "So keeping him fit during the process has been a challenge for him and one that he’s attacking.”
One could argue that the team was too persnickety with Brown. His biggest task as an NFL tackle, after all, is keeping the quarterback's jersey clean, and he was very good at that. The New England Patriots, who presumably put Brown on a scale and gave him a physical before signing off on the trade, will rely on him to keep Tom Brady, who will be 41 when the regular season begins, healthy. The Patriots don't exactly have a reputation for being lax as far as the type of players they bring in.
But Friday's moves in Santa Clara underscore the same thing: The 49ers are looking for a certain type of guy in their locker room.
Tartt and McGlinchey fit the mold. Brown did not.
