Who would have expected, back in 1999, that the Greatest Show on Turf banner would be carried all the way into 2012 by the undersized, undrafted London Fletcher? He and the Washington Redskins have apparently agreed to a two-year contract extension, keeping him in the capital through his age-38 season.
Fletcher's shown little sign of aging since joining the Redskins, earning Pro Bowl berths in 2009, 2010, 2011, and 2012; he's not as active as he once was against the quarterback, but that's all that's changed since his Rams stint. (Aside from, say, cell phones, which have changed considerably more.) More impressively still, he's never missed a game—not in St. Louis, not in Buffalo, and not in D.C. (What makes that especially hard for me to believe is that he's initiated 1242 tackles in that span.)
24-years-old during that incredible 1999 season, so far as I can tell London Fletcher appears to be the last active member of those Rams now that Torry Holt has officially retired. Leonard Little was the last of that team to play for the Rams, retiring in 2009 after 87.5 career sacks.
