Packers quarterback Aaron Rodgers isn't overly concerned about his team's lackluster offensive performance on Monday. When asked about the practice, Rodgers imitated Allen Iverson's infamous rant. "Practice? We talking about practice?" Rodgers said. "We're not talking about a game. We're talking about practice. ... Uh, practice? I'm not overly concerned. It was a tough environment inside. We just have to clean things up a little bit. Too many mental mistakes." Green Bay coach Mike McCarthy publicly laid into his team for the lackluster effort on Monday, citing a number of fumbles. With a defiant "no," Rodgers dismissed the notion that not getting together during the off-season for workouts had any carryover effect into training camp.
