San Francisco 49ers QB Colin Kaepernick takes vocal lead

SANTA CLARA, Calif. -- Colin Kaepernick has taken some criticism for not being a more vocal leader, but the San Francisco 49ers quarterback certainly had no issue speaking out during practice Tuesday at the start of the team’s three-day mandatory minicamp.

During an 11-on-11 scrimmage he noticed one of the team’s young wide receivers not running a route at full speed. Kaepernick loudly chastised the receiver twice while walking back and forth on the sidelines.

“What you stopping for? Run,” Kaepernick said. “That’s your job.”

It was a bit out of character for Kaepernick, who tends to be more laid back in the locker room than other quarterbacks around the NFL. That quiet approach led to some people being critical of San Francisco’s veteran quarterback, though 49ers coach Jim Tomsula doesn’t understand why.

Tomsula, who was hired after the 49ers parted ways with former coach Jim Harbaugh, said Kaepernick is doing just fine as a team leader and that he wants “Colin to just be Colin.”

“People lead in different ways,” Tomsula said. “There’s different styles of leadership. Some people talk a lot, some people don’t. Some people speak volumes without ever opening up their mouth. Be a great teammate, the things that he’s doing right now. Where Colin’s at right now, who he is and what he’s doing, I’m his number one fan.”

Other news and notes from Tuesday’s practice:

  • New 49ers running back Reggie Bush looks as quick as ever, a good sign for a team trying to compensate for the departure of Frank Gore. Bush moved swiftly through multiple agility drills and quickly scooted downfield to haul in a long pass from backup quarterback Blaine Gabbert during pass drills.

  • Second-year running back Carlos Hyde dropped a long pass from Kaepernick during the same drill, drawing playful jeers from some of his teammates. Hyde later let a swing pass from Kaepernick slip through his hands.

  • Alex Boone spent most of the workout lining up at left guard with the second-team offensive line instead of his normal spot at right guard. Boone is also likely to get some time in at right tackle, according to Tomsula. Andrew Tiller worked out at left guard while Marcus Martin took reps at right guard with the first-team offense. Brandon Thomas and Ian Silberman also practiced there with the backups. Erik Pears started at right tackle and was backed up by Trent Brown and Justin Renfrow.

  • Linebacker Michael Wilhoite made a nice play to intercept a Kaepernick pass that deflected off Boldin’s hands. Two plays later, Kaepernick found wide receiver Torrey Smith for a long gain.

  • One of the biggest concerns the 49ers have this offseason is finding out who their starting cornerbacks will be. Keith Reaser, a fifth-round pick in 2014 who missed all of his rookie season while mending from a torn ACL, started at one cornerback spot in practice Tuesday while Dontae Johnson was at the other corner. Tramaine Brock is also likely to be part of the equation, though he’s been held out of all team drills this offseason with what’s believed to be a hamstring injury. Kenneth Acker, Marcus Cromartie, Chris Cook and Shareece Wright figure into the mix as well.
