RICHMOND, Va. -- Redskins.com's Ryan Fowler breaks down the key plays and highlights from Day 6 of training camp at the Bon Secours Washington Redskins Training Center on Wednesday.

Offense:

-- The offense experienced its share of highs and lows Wednesday. Josh Doctson and Kelvin Harmon led the day for the receivers, each showing off their ability to high point the football. Doctson was unstoppable in 1-on-1 red zone drills, going over the top on Quinton Dunbar and then reeling in a one-handed catch on rookie Jimmy Moreland.

-- Haskins completed all six of his passes during 7-on-7 drills and continued to look sharp during 11-on-11s, launching a well-placed deep ball on a wheel route that running back Byron Marshall ultimately dropped. On another play, the rookie quarterback displayed increased command in the offense, motioning Adrian Peterson up in the backfield to pick up a blitzing defender before hitting Cam Sims for a short completion.

-- Newest Redskin Donald Penn worked exclusively at left tackle with the third offense. Penn mentioned how the "familiar faces in Washington" have allowed the 14th-year tackle to quickly learn the offense after working with Jay Gruden's brother, Jon, in Oakland. With both Chase Roullier and Geron Christian now practicing, the starting offensive line has begun to develop chemistry that has resulted in bigger running back lanes and decreased pocket pressure.

Quick Hits:

• The tight end group enjoyed another productive session. Jordan Reed continued to dominate, while Jeremy Sprinkle and Vernon Davis each caught touchdown passes. On Davis' score, Colt McCoy lofted a gorgeous ball over linebacker Josh Harvey-Clemons, who was tight in coverage.

Defense:

-- Defensively, Caleb Brantley stood out Wednesday. The third-year defensive tackle frequented the backfield and looked visibly upset when he wasn't in the backfield wrecking havoc.

-- Tempers flared between the offensive and defensive lines during 1-on-1 drills and eventually resulted in a scrum during team drills that prompted Gruden to temporarily scrap the period. As the skill players engaged on more 7-on-7 work, both lines ran sprints on the side field before returning to action.

-- Defensive coordinator Greg Manusky continued to show a three-safety look during full team drills. The defensive package showed Montae Nicholson, Troy Apke, and Deshazor Everett all at safety across the back of the defense with two corners on the outside. The package allows Everett to roam the box both in coverage and blitz situations. At times, Everett stayed put in the middle of the defense throughout plays as a spy.

-- Josh Norman uniquely disguises his coverages. Sometimes he'll press the line and then retreat, and other times he'll start 10 yards off the receiver and then sprint into press coverage. Norman continued to make plays Wednesday, with his highlight coming when he jarred the ball loose against running back Byron Marshall after a short reception. Rookie Cole Holcomb scooped up the fumble and was off the other way for a would-be touchdown.

Special Teams:

-- Trey Quinn, Greg Stroman, and Jimmy Moreland all practiced returning punts.

-- Special Teams coach Nate Kaczor has been vocal throughout practices thus far in Richmond. During punt return and field goal drills, Kaczor can be heard screaming "knock him back," in an effort to stress the importance of physicality within special teams sets.
