Both first-round draft picks signed five-year contracts a few hours apart, ensuring the highly touted offensive linemen will be in uniform for Sunday's first training camp practice.
Davis was the No. 11 overall pick in this year's draft and Iupati was selected by the 49ers six picks later. With their stalls next to each other in the team's locker room, there hasn't been much to separate the two burly youngsters who are expected to immediately challenge for starting spots.
"We've kind of had that bonding, that brotherly bonding, just that we wanted to be on time and try to get a starting spot," said Iupati, the last of the team's eight draft picks to sign.
The headliners Friday were Davis and Iupati, whom the 49ers were eager to get into camp early so they can begin their quest to bolster an offensive line that has been one of San Francisco's weakest areas in recent seasons. Davis will compete at right tackle and Iupati will get his starting shot at left guard.
Davis signed a deal worth a reported $26.5 million with almost $16 million guaranteed. Iupati's deal could be worth as much as $18.25 million with $10.8 million guaranteed.
"That was the biggest priority," Davis said. "That's why I wanted to get done first, so I could get in and hit the ground running. It's done and out of the way, and now we can do what I'm here for."
While Davis and Iupati were brought in to help the offense, Mays and Bowman will make their mark on defense for a team tabbed by many as the NFC West favorite this season.
Mays and Bowman each were selected to several All-American teams last year. Mays will challenge for playing time at safety and Bowman is expected to compete at linebacker and contribute on special teams.
Along with the rest of San Francisco's rookies, both hard-hitting defenders are eager to put on the pads.
"That's football, and I feel that's a strong part of my game," Mays said. "It's always good to get the pads on because you get to show a little more than you do when you just have helmets on. That's kind of what separates some guys from other guys, and I think that will be what happens when we get the pads on."
Said Bowman: "Like a lot of people say, we're only going to go as far as the rookie class will take it. We have to be on point and ready to go."
