Ricardo Lockette is so intent on landing a spot on the 49ers' roster that he bought a white board and markers so he could chart and study plays on his own time. Lockette also has an expert checking his homework: 49ers quarterback Colin Kaepernick. "If we have new things going in (the playbook), I'll have him draw them up – different formations, different coverages," Kaepernick said. "It's making sure he knows his adjustments and knows where everyone is lined up on the concept." Lockette, 26, one of several undistinguished wide receivers fighting for a roster spot, has two notable advantages. First is his access to the most critical player on the team. He and Kaepernick had instant chemistry when they met in February 2011, and they have been housemates since the 49ers added Lockette to the practice squad Sept. 25. They also spent the early part of the offseason training together near Atlanta. Kaepernick, borderline maniacal when it comes to offseason conditioning, said he seeks training partners who will push him. Who better to do that than the fastest player on the team? "I did a few track workouts with him," Kaepernick said. "And it's unbelievable the speed he has, and it's just natural to him." Tyree Price, Lockette's track coach at Fort Valley State University in Georgia, thinks speed could have landed Lockette in the Olympics. In his first 200-meter race at Fort Valley State, Lockette was so far ahead of the field that he began proudly – and cockily – pointing to the stands 30 meters before the finish line. Lockette still finished in 20.69 seconds, but Price admonished him. "There's a way to win," he told the young sprinter. Price said he's certain Lockette could have run the 200 in the 19-second range had he stuck with track. Only half of the eight finalists in the men's 200 at the London Olympics finished in under 20 seconds. Gold medalist Usain Bolt won in 19.32.
