Wide receiver A.J. Jenkins claimed he doesn't "go on the Internet and Google my name. There's no point."
But Jenkins, this year's first-round draft pick, still heard the criticism after his May 12 debut at a rookie minicamp.
"I've made long strides," Jenkins said. "Obviously, I had criticism when I first came in as far as being in shape. That's irrelevant now. I'm just trying to help the team win, whether that's playing special teams, offense or being a real good teammate."
Monday marked the first practice of training camp for rookies, along with all four quarterbacks and selected veterans. The first full-squad workout is set for Friday, a day after all veterans must report.
"It's good for us to have like an extra week of practice, get back into the playbook and back into football shape," Jenkins said. "The feeling of a football camp is definitely here, though."
Jenkins took part throughout a "pretty intense" offseason workout program and signed his four-year, $6.95 million contract last month.
Still on his to-do list: Take up Jerry Rice on an invitation to run his famed training hill in San Carlos. Those plans are on hold during camp, though Jenkins hopes to "one day" get in contact with Rice.
Jenkins instead has sought advice from in-house veterans Randy Moss and Mario Manningham on how to prepare his body for camp. "My mindset has really been a lot stronger since the first day of rookie minicamp," Jenkins said.
Ginn's objective Monday: "Come in early with the young guys, fly around and do certain things out there to see where I'm at." His sure-handed approach on punt returns was sorely missed in the NFC final, where replacement Kyle Williams botched two returns in a 20-17 defeat to the New York Giants. Ginn appears stronger in the upper body and said he has tacked on 10 pounds to his now 185-pound frame.
Listed as a cornerback by the 49ers, McBath played safety his first two seasons with the Broncos under secondary coach Ed Donatell, who now holds the same position with the 49ers. McBath said he's fully recovered from a broken arm he suffered in his only game last December with the Jacksonville Jaguars.
