With training camp set to begin next week, Redskins.com's Andrew Walker previews the current state of the Redskins' roster, starting today with the team's quarterbacks.

Last season, the Redskins went into their first year of training camp at the Bon Secours Training Center with four quarterbacks at their disposal.

This year, pending any last-minute moves, the team heads back to Richmond, Va., with one less arm – but with plenty of experience within the position, nonetheless.

ROSTER SUBTRACTION(S):- Quarterback Rex Grossman (unrestricted free agent)

KEY ADDITION(S):- Quarterback Colt McCoy (free agent)

CURRENT STATE OF THE UNIT:Quarterback is one of the more stable positions on the Redskins' roster.

Robert Griffin III returns for his third year as the team's starter and hopes to return to his 2012 form, when he was named the NFL's Offensive Rookie of the Year and led Washington to its first division title since 1999.

But that's not to say Griffin III didn't have flashes of brilliance last year. An offensive captain (as voted by his teammates), the Heisman winner in 2013 started and played in each of his team's first 13 games, finishing with 3,203 yards passing and 16 touchdowns, while also adding 489 rushing yards. And all this came after undergoing major knee surgery prior to the season, and never getting the chance to fully train in the offseason.

Backing Griffin III up this season will be Kirk Cousins and McCoy. Cousins last season took over for Griffin III in the team's final three games of the season, becoming the first Redskins quarterback in the Super Bowl era to throw for 300 yards in each of his first two career starts.

McCoy, meanwhile, is a veteran that brings four-plus years of experience to the Redskins' quarterback room. He enters 2014 having appeared in 28 regular-season games with 21 starts, completing 410-of-703 passes for 4,401 yards with 21 touchdowns with the Cleveland Browns and San Francisco 49ers.

WHAT TO WATCH:Now with a full offseason at his disposal, those around Griffin III – who has said he will ditch his knee brace – believe the Baylor product could put up some monster numbers in 2014.

Factor in the team's potent rushing attack and the additions of wide receivers Andre Roberts and DeSean Jackson this offseason, and it's not hard to fathom Griffin III being the leader of a Top 5 offensive unit this year.

But as far as training camp goes, be sure watch the competition for the backup quarterback spot.

Cousins has established himself as the team's No. 2 quarterback in his two-plus years in D.C., and his relief appearances for an injured Griffin III in 2012 were major reasons why the team was able to win the NFC East title.

But despite the fact McCoy has not started a game since the 2011 season, he adds a quality veteran presence and has plenty of experience in the backup role – something he did last season for Colin Kaepernick and the San Francisco 49ers, who appeared in the NFC Championship game for a third-straight season. Also, don't be surprised if general manager Bruce Allen decides to bring in a fourth quarterback for training camp purposes, which adds an extra arm to the mix to ensure the wide receivers, tight ends and running backs are getting quality reps.
