GREEN BAY, Wis. -- Brett Favre was 36 when he reported to Mike McCarthy’s first training camp as the Green Bay Packers' new coach in 2006. By then, McCarthy already had decided to limit how much his veteran quarterback would throw during training camp.

Ten years later, McCarthy has to start thinking about the same thing with his current quarterback, Aaron Rodgers. At age 32 and entering his 12th NFL season (his ninth as a starter), Rodgers might be in the best shape of his career. McCarthy raved about Rodgers’ conditioning when he reported for training camp Monday.

And after two days of practice, the difference in Rodgers' workload compared to seasons past appears negligible, if there's any at all.

"If you look at the team periods yesterday, if you do track that, you wouldn’t see a big variance in rotation snaps of the [Nos.] 1 and 2 [quarterbacks] as opposed to prior years," McCarthy said before Wednesday’s practice. "But on the other side of that, we are conscious of how much Aaron’s throwing the ball. That’s something we need to be conscious of."

In practice on Wednesday, Rodgers took the first four snaps of the opening 11-on-11 period, and Brett Hundley took the next four. Rodgers returned for two more before third-stringer Joe Callahan jumped in. In the next team period, Rodgers took the first three snaps followed by two for Hundley, two more for Rodgers and then three more for Hundley.

With an extra preseason game this summer because of their appearance in the Aug. 7 Hall of Fame game in Canton, Ohio, the Packers will have plenty of time to prepare Rodgers for the Sept. 11 opener in Jacksonville and also work in Hundley, who is entering his second season, but his first as the No. 2 quarterback.

Last season, Rodgers played two of the four preseason games. Even with five games this preseason, his game reps might not increase much, especially if receiver Jordy Nelson doesn’t suit up.

"The fifth preseason game, nobody’s going to benefit from that more than Brett Hundley, no doubt," McCarthy said. "We want to see Brett play as much as he possibly can, and then from that make sure what’s going on around him and make sure you’re getting the other two guys [Callahan and Marquise Williams] their opportunities. So the fifth preseason game will benefit all of our younger players, and definitely will benefit Brett Hundley."

Still, no one is more important to the Packers’ success than Rodgers, who agreed with McCarthy’s assessment of his conditioning.

"I’m as light as I’ve been in a while, but my muscle mass is as strong as it’s been when I’ve been 10 pounds heavier," said Rodgers, who is listed at 225 pounds but weighed 218 this offseason thanks to a new nutrition plan.

"That was the goal as I get older, was to continue to find ways to get my nutrition and my muscles where I need them to be, and I feel good about where I’m at. Conditioning is something that kind of grows throughout camp but, coming in, I’m physically in as good of shape as I’ve been in a while."
