The 49ers wrapped up their three-day mini-camp Sunday and the session was just as spirited as the first two. There was plenty of good-natured smack talk, such as when Vernon Davis - emerging as the king of smack talk - scored during a red-zone drill and then got in the face of linebacker Brandon Moore. Following a running play, the defensive line vociferously accused right tackle Kwame Harris of holding. Harris responded by ripping off his jersey and tossing it to the defense, an appropriate comeback to Manny Lawson's shirt-throwing antics a day earlier. Overall, the group looks loose and confident. Coach Mike Nolan, however, gathered the team after practice and warned them about being overconfident. "Obviously there's a lot of optimism out there, but we've got a lot of work to do he said." The team will next meet as a group on June 4 for the beginning of off-season team activities or OTAs.
*Fourth-round draft choice Jay Moore weighs 273 pounds, but is so quick and lean you'd swear he was closer to 240 pounds. Nolan said that by the time the season rolls around Moore probably will be in the upper 260s.
*Speaking of weight, new outside linebacker Tully Banta-Cain admitted he currently weighed 280 pounds. He said that the rigors of OTAs and training camp will get him down to his natural playing weight - about 265 pounds.
*Brandon Williams said he switched numbers because he wanted to be known as a receiver, not just a return man. He went from No. 17 last year to a more receiver-like No. 81 this year.
*Ronald Fields played left defensive end during the mini-camp. When Bryant Young returns, however, Fields may be moved to the right side.
*Receiver Ashley Lelie said he did not tear his quadriceps while running a pass route Friday and that he expects to be back in action by June 4. Fellow receiver Darrell Jackson (toe) and all the other players who had off-season surgery won't be back until training camp, which begins July 29.
