GREEN BAY, Wis. -- Here's a look at what stood out from the Green Bay Packers' second open OTA session of the offseason Tuesday:
1. Rookie catch up: Second-round receiver Davante Adams and third-round defensive tackle Khyri Thornton returned after missing last week's OTA sessions to attend the NFL Players Association Rookie Premier event. Adams said he stayed in his playbook during the trip to and from Los Angeles. "When I was out there, I was studying my playbook," Adams said. "When I was on the flight, I was studying my playbook. That's pretty much all it was."
2. Boykin, Harper shine: Receivers Jarrett Boykin and Chris Harper had big days during team and 7-on-7 passing periods Tuesday. Both stood out during the team blitz period, catching hot reads from quarterbacks Aaron Rodgers and Matt Flynn. Boykin has been working as the No. 3 receiver despite the arrival of Adams and fellow draft picks Jared Abbrederis and Jeff Janis. Harper, a fourth-round pick of the Seattle Seahawks last year, was claimed off waivers last Oct. 18 and is an intriguing prospect with good size (6-foot-1, 228 pounds). "Chris has really improved," Packers coach Mike McCarthy said after practice. "I mean, I think you saw the first snap there in the team period, I mean, he runs a great post and Aaron hits him right in stride. I mean, that's the kind of explosiveness that he has."
3. Barclay's versatility: Third-year pro Don Barclay is making a case for being the team's most versatile offensive lineman. He worked with the starters at left guard Tuesday, when Josh Sitton appeared to be limited. Last week, Barclay worked at right tackle behind Bryan Bulaga. He also could take reps at center. At this point, Barclay looks like he might be the team's top backup linemen at several positions. "Donny has the ability to potentially play five positions on the offensive line," McCarthy said. "I don't know how many guys you can say that about."
4. Inside pass-rush combination: It looks like defensive coordinator Dom Capers is going to give Datone Jones and Mike Daniels every chance to be his primary interior pass rushers in the sub packages. The Packers hope Jones can make the kind of jump Daniels made last year, when he increased his sack total from 2 to 6.5.
5. Another new guy: With B.J. Raji absent from Tuesday's practice, Letroy Guion took most of the reps at nose tackle with the starters. Guion, the former Minnesota Vikings defensive lineman who signed a one-year deal with the Packers this offseason, gives the Packers a taller option at the spot. He has two inches on the 6-2 Raji.
6. To the House: Fourth-year cornerback Davon House, who is coming off an inconsistent season, came up with an interception during a team period, when he picked off a corner route thrown by Flynn that was intended for Kevin Dorsey.
7. Kicking competition: There's not another kicker on the roster this year, but it's still worth charting all of Mason Crosby's field goals. He went 7-for-8 during a team period on a windy Tuesday. His only miss was wide right from 47 yards. He also missed from 43 yards, but that kick was whistled dead at the snap and therefore did not count. Last year at this time, Crosby was kicking for his job. This year, he's coming off a career-best season in which he made 89.2 percent of his regular-season field goals.
9. Roll call: Add cornerback Jumal Rolle to the list of those who did not practice. McCarthy does not give injury updates during OTAs, and Rolle was not available for comment. Others who did not practice due to injuries were: running back Johnathan Franklin, linebacker Clay Matthews, linebacker Nick Perry, tight end Andrew Quarless and tight end Brandon Bostick. Those five also missed last week's sessions.
10. Roll call, part II: Rookie tight end Colt Lyerla, defensive end Jerel Worthy and Raji were not in attendance. Lyerla's agent, Vinnie Porter, said the Packers were aware of Lyerla's absence in advance and excused him even though that was not necessary because it is a voluntary workout. McCarthy said he expected Lyerla back Wednesday. Worthy's grandmother died last week after she was accidentally shot.
The Packers' next open OTA session is next Tuesday at 11:30 a.m. local time.
