Jim Harbaugh is fond of saying that all of his players have "the license" to compete for starting spots.
"It applies to everybody," the San Francisco 49ers coach said at the start of the team's rookie minicamp on Friday.
Harbaugh was also talking about center
"Right now," Harbaugh said, "he's the understudy. That's the expectation we put on him, to learn, to get up to speed as fast as possible and put no timetable to it."
"I'm coming in to compete," Martin said. "I'm learning as much as I can from Kilgore and the rest of the offensive line.
Davis, in particular, can relate to the USC product. He entered the NFL at age 21 in 2010. Martin is still just 20 entering his first minicamp.
"One thing Anthony emphasized is age doesn't have anything to do with your ability to play on the field," Martin said. "His birthday is in October. Mine is in November. He told me, 'Don't worry about your age. Just come in and compete.' That's what I'm worried about."
Martin added that he has seen similarities to the offense he ran in the Pac-12 to that of Harbaugh and his staff here. He'll be playing center and both guard positions this weekend.
