With free agency set to begin in March, Redskins.com's Stephen Czarda previews the 2016 NFL free agent class position-by-position. Today's focus is on the quarterbacks.

As the Washington Redskins and Trent Williams continue to try to come sort of contract agreement, whether it be of the long-term variety or with the franchise tag for the 2016 season, the team may be in the market for quarterback depth.

Veteran Colt McCoy just completed his second season with the Redskins, appearing in just two games, and is going to be a pending free agent.

After playing just three plays against the New Orleans Saints, all handoffs, McCoy saw significant action in the regular season finale against the Dallas Cowboys, completing seven of 11 passes for 128 yards and a touchdown.

In his first season with the Redskins, McCoy appeared in five games with four starts, throwing for 1,057 yards and four touchdowns to three interceptions with a 71.1 completion percentage.

Trent Williams, meanwhile, the No. 2-overall pick in the 2012 NFL Draft, was inactive for all but one game during the 2015 season and the team can choose to not pick up his fifth-year option before March 9, making him a free agent in the process.

Griffin III, of course, had one of the most memorable rookie seasons in recent history in 2012 before dealing with injuries and inconsistences over the next two seasons.

Here is a list of the quarterbacks scheduled to become unrestricted free agents at 4 p.m. ET March 9, via NFL.com:

--Sam Bradford, Philadelphia Eagles

Bradford spent the 2015 season with the Eagles after being drafted by the St. Louis Rams and playing his first five seasons with the franchise.

While Bradford has at times flashed the potential that made him the No. 1-overall pick in 2010, the Oklahoma product has appeared in all 16 regular season games just twice while dealing with two torn ACL along with other injuries.

Hasselbeck, meanwhile, is the oldest quarterback in the NFL as he'll turn 41 years old before the start of the 2016 season.

Although he wasn't expected to see much action as the Indianapolis Colts' backup to Andrew Luck last season, he ended up starting eight games, throwing for 1,690 yards and nine touchdowns.

Another well-known veteran is Vick, who signed with the Pittsburgh Steelers last season.

Vick, 35, remains one of the best dual-threat quarterbacks in history, as the Virginia Tech product has accumulated nearly 22,500 passing yards and 6,109 rushing yards in his career.
