Rookies July 25th, Veterans July 27th SITE: St. Norbert College, De Pere, WI CAMP OBJECTIVES: The Packers were 25th in the league against the pass last season and gave up 23.8 points per game, problems that the franchise hopes new defensive coordinator Jim Bates can fix. He'll have his work cut out for him, as Green Bay failed to make a single personnel upgrade at any spot on the defensive side of the ball. The biggest concern will be at cornerback, where Al Harris is solid but far from spectacular and second-year players Ahmad Carroll and Joey Thomas have yet to impress. Newbies Earl Little (Browns) and Arturo Freeman (Dolphins) will be in line for the starting strong safety job, and Cardinals castoff Ray Thompson will likely take over at one outside linebacker slot. On offense, Brett Favre must prove he can thrive without longtime starting guards Marco Rivera (Cowboys) and Mike Wahle (Panthers), both of whom slipped away in the offseason. Free agent acquisitions Adrian Klemm (Patriots) and Matt O'Dwyer (Buccaneers) are slated to take over at guard, but neither is considered to be of first-rate vintage. Head coach Mike Sherman will take a long training camp look at first-round draft choice and quarterback Aaron Rodgers (Cal), who is unlikely to get on the field this season but is considered the heir apparent to Favre. Punter B.J. Sander, a major disappointment in 2004 training camp, will get another chance to win the job after Bryan Barker was not tendered a contract for '05. PRESEASON SCHEDULE: vs. San Diego (8/11); at Buffalo (8/20); vs. New England (8/26); at Tennessee (9/1)
