The good: Wide receiver Donald Driver is a man on a mission. After offseason speculation that he could be released, Driver, 37, agreed to restructure his contract (taking a pay cut from $5 million to $2.5 million) to return to Green Bay for a 14th season and now seems driven to prove his doubters wrong. He’s had a strong training camp, and Tuesday was easily his best day. In a team red-zone session, Driver scored twice, putting on an absolute clinic. First, he took second-year cornerback Davon House to school, shaking himself free for a wide-open touchdown. Then, minutes later, he displayed glue hands, snaring a laser-beam throw from Aaron Rodgers to score over Jarrett Bush. If that wasn’t enough, in the two-minute drill, Driver scored on a 20-yard seam route for his third touchdown in about 15 minutes. On the other side, safety Morgan Burnett also had his best day of camp. He was active, intimidating and disruptive in pass coverage. After practice, coach Mike McCarthy said Burnett was “ready to step into the forefront.”

The bad: It seems like piling on at this point, but once again Sam Shields did nothing to help close the quickly widening gap between himself and the other cornerbacks. Up for grabs are the No. 2 job on the outside opposite Tramon Williams and the nickel and dime spots. Shields, the No. 3 CB last year, has had a frightful start to camp and fallen behind veteran Jarrett Bush and second-year man Davon House. He wasn’t as bad Tuesday, but he was far from good, and he needs to make some impact plays to get himself noticed for a positive reason. On the last play of practice, Shields, who actually had good position on wide receiver Tori Gurley in the end zone, didn’t get his head turned around quickly enough and surrendered a touchdown. McCarthy said afterward that Shields was getting better but still needs much improvement. He said Shields relies too much on his speed and needs to refine his technique.

The newsworthy: Tight end Jermichael Finley was back in full pads after being limited  on Monday and missing the previous two days with a concussion. He looked undaunted going over the middle, catching a few darts from Rodgers in traffic. Finley said in June that he attributed his inconsistency in 2011 to being apprehensive and cautious of injury. If he can regain his confidence and fearlessness, he could have  monster season in 2012.
