Chargers camp report: Day 2

SAN DIEGO -- A daily review of the hot topics coming out of San Diego Chargers training camp:

Play of the day: Edge rusher Dwight Freeney once again showed that he's close to being fully healthy, blowing by left tackle King Dunlap in a one-on-one pass rush drill. Freeney refused to put a percentage on his recovery he sees live action in exhibition play, but so far the explosiveness he's shown on a regular basis during practice has been one of the highlights of camp for San Diego head coach Mike McCoy.

"With players like that, they know what it takes to get back and to work," McCoy said. "And they know their bodies better than anybody else. Where, compared to a younger player, they might feel it out a little bit. But when you're a true pro like he is, and has had the success he's had and the burning desire to be the best, it doesn't shock me one bit."

Position watch -- offensive line: Watching Chargers offensive line coach Joe D'Alessandris during practice makes you appreciate the high level his unit executed at last season.

The group works at a frenetic pace, with an enthusiastic, high-energy D'Alessandris leading the drills. Few moments are wasted, and D'Alessandris emphasizes teaching over screaming instructions.

Versatility also remains important for a unit that played six different offensive line combinations last season, with players rotating to different positions along the line during individual drill work.

"Depending on any situation that might arise, everybody knows what they're doing, and there's continuity within the group," offensive lineman Rich Ohrnberger said. "They work us hard, and we've had a lot of success because of it."

Injury report: Offensive guard Jeromey Clary (shoulder,hip) remains on the active, physically unable to perform list. Clary's replacement, Johnnie Troutman, returned to practice as a full participant after leaving practice on Thursday with what appeared to be a hamstring injury.

Up next: The Chargers hold their first padded practice on Saturday at 12:20 p.m. ET. The practice will take place at Chargers Park, and is open to the public.

You don't say: "Over the past month I just went home and studied the playbook, worked out a lot. And I've just come back now and I'm playing more comfortable and confident."

-- Chargers rookie receive Tevin Reese, who has looked impressive during the first two days of camp. McCoy mentioned Reese as one of the young players who has stood out during the early portion of training camp.

Coach's corner: The open competition for the return jobs continued on Friday, with young players like Brelan Chancellor, Kerwynn Williams, Marion Grice, Chris Davis and Reese sharing reps with proven returners Eddie Royal and Keenan Allen.

While the practice reps are important, McCoy said ultimately the return jobs will not be decided until he sees players in live action in preseason games.

"We're not going to tackle the returners out here in practice," McCoy said. "So we're going to have to wait to see some of those younger players in preseason. They'll get a lot of shots, and a lot of opportunities."
