Although Barnett just joined the Redskins last offseason, he could have already played his last game with the team. The 32-year-old failed to make much of an impact this season, recording just 12 tackles in a reserve and special teams role. He had previously been a starter in Green Bay -- where he spent his first eight seasons -- before putting together consecutive 100-tackle seasons in Buffalo in 2011 and '12.
In fact, Barnett's 11-year NFL career could be over entirely. He'll be 33 in May and coming off of a major knee injury, which doesn't bode well for his chances in free agency.
The 2003 first-round pick has piled up a wealth of stats during his time in the league, including 1,041 combined tackles, 20.5 sacks, seven fumble recoveries and 12 interceptions.
