ProFootballTalk.com's Top 25 In 25

No. 19:  Darrell Green.

Like Junior Seau at No. 20, cornerback Darrell Green became an NFL institution by spending so many years in the NFL that it was hard to remember when he first arrived.

In Green's case, he joined the Redskins in 1983 -- and spent 20 seasons with the same team.  For a guy whose ongoing employment hinges on speed and agility, the fact that he could remain on the one squad's roster for 20 seasons is amazing.  The reality that 10 of those seasons came in the free-agency era, which has resulted in many a veteran being purged from his team prematurely, boggles the mind.

Along the way, Green won two Super Bowl rings, and played a key role in the march to the team's 1987 NFL championship with a game-changing punt return against the Bears.

At a mere 5-9, Green was for years one of the fastest players in the NFL, winning on multiple occasions a made-for-TV sprinting competition with other fleet-footed football players.

Green most certainly will land in the Hall of Fame in 2008, his first year of eligibility.  He deserves it, and he definitely deserves a spot among the best 25 players of the past 25 years.  He might just be one of the best 25 ever.
