SANTA CLARA — Frank Gore got mad at the television last week at the 49ers' team hotel. Replays of Super Bowl XLVII appeared, and Gore's anger returned over a lost Lombardi Trophy.
The next day, after his first practice of training camp, Gore adamantly staked his claim for 2013.
"I respect all my guys here. I'm glad they push me," Gore began. "But I'm being real: I train like I still want to be The Man. I really do. I'm not ready to pass the baton yet."
Overshadowed by the emergence of quarterback Colin Kaepernick, Gore isn't about to minimize his impact on another possible Super Bowl run. Nor is he giving up the copyright to run behind an elite offensive line.
"That's what makes him great," right tackle Anthony Davis said. "If you look at him on the field, he looks like a rookie. Coaches have to pull him out of drills. He's trying to impress himself."
Eight years after arriving as a third-round gamble with surgically repaired knees, Gore's passion for football burns like an eternal flame inside his 5-foot-9 cauldron.
His constant search for validation could stop easily at the 49ers' record book, where he holds all major rushing records: 8,839 yards, 1,911 carries and 51 touchdowns.
But Gore knows how 30-year-old tailbacks are viewed.
"People like to say what happens at 30," Hall of Fame running back Marshall Faulk said. "He'll find out. It has nothing to do with skills. It's the nature of the position. A boxer can take only so many punches, a tire has only so much tread. It's about being prepared for it."
Outside of conditioning in the 49ers offseason program — an undisclosed injury kept him out of team drills — Gore also worked out in his native south Florida with personal trainers, including Pete Bommarito and Terek Maddox.
