The Packers are used to seeing Julius Peppers twice a year.

Their first workout with him on their side had them excited about the possibility of 16.

Teammates were impressed by Peppers’ first OTA workout, and are already thinking about what he’s capable of.

“You obviously notice his athletic ability right off the bat,” linebacker A.J. Hawk said, via Lori Nickel of the Milwaukee Journal Sentinel. “He’s 34 and runs like he’s 18. If ever there was a genetic freak put on this planet, it is Julius. He’s just a specimen. I have a ton of respect for how he works, too. What a great teammate just from Day 1. He’s a quiet guy that already knows what he is doing, so it is fun to be around a guy like him.

“Him being in Chicago all these years, and getting to see him up close and personal two games a year, is always something I’ve been impressed by. Now, to have him on our side, to see how good of a guy he is, how good of a teammate he is, he’s already lived up to — and exceeded — my expectations.”

Peppers has created a high bar for himself because of his natural gifts. While it’s easy for someone so large and so graceful to appear effortless and thus draw criticism, he’s compiled 118.5 sacks and ranks in the top 20 all-time in that category.

They’ve all come from a 4-3 defensive end spot with the Bears and Panthers, and the Packers are using him as a hybrid outside linebacker (hence the unfamiliar number 56).

But so far, they’re excited about what they’ve seen, and what he might add as a pass-rusher opposite Clay Matthews.
