GREEN BAY, Wis. -- In a little more than five weeks of training camp, the Green Bay Packers spent less than a day and a half in real time on the field.

But that shouldn’t be mistaken for an easy camp, according to coach Mike McCarthy.

“This is the highest intensity that we’ve ever had in so many practices,” McCarthy said this week.

That isn’t some arbitrary assessment, either. McCarthy says he has the data to back it up. The Packers track every player’s movement during practice by GPS devices implanted in their pads.

“The quality of our training camp from a pure analytics standpoint, this is the best year we’ve ever had as far as just the energy, the physicality,” McCarthy said. “Since we’ve been doing the numbers over the last four or five years, this is the highest intensity that we’ve ever had in so many practices.

"You have comparables and what you do with those numbers is most important because statistics don’t always tell you everything, as you know. But how it gives you the opportunity to regulate different periods, and it’s not only how you do it but it’s when you do it. That really helps get the intensity and get the numbers as high as you possibly can. We definitely achieved that this year.”

In real time, the Packers spent 34 hours and 21 minutes on the field in their 17 practices (including Family Night at Lambeau Field) that were open to the media. In the same number of sessions last summer, they practiced for 31 hours and 48 minutes. In 2014, they were on the field for 35 hours and 30 minutes.

“I think you have to go a lot further than that,” McCarthy said when asked about total time on the field. “You can’t just look at how many days you’re on the field. I think that’s the starting point, if anything. You have to look at the reps. You have to look at how many reps you’re getting in certain periods.”

McCarthy pointed to the spirited, physical half-line rushing drill as a prime example.

“We’ve never ran the number of reps in the half-line drill that we’ve had this year,” he said. “So you’ve got to look at each period, how many reps you’re getting in each period, the fundamental drills. I mean, everything is weighted. As far as that aspect of it, it’s been an excellent camp.”

The era of two-a-day practices in camp is long gone; the labor agreement of 2011 took care of that. With that in mind, here’s a look at some of the training camp superlatives:

• Longest practice: 2 hours and 42 minutes, Aug. 23

• Number of practices longer than 2:30: Five

• Shortest practice: 1 hour and 35 minutes, Aug. 30

• Number of practices less than two hours: Seven

• Average practice time: 2 hours and 1 minute.
