Matt Birk will retire while on top this Friday. The starting center for the Super Bowl Champion Ravens is calling it quits after 15 seasons in the NFL. During his 15 seasons, he was elected to the Pro Bowl six times and was named an All-Pro twice. Other awards include a 2006 Block Courage Award and a 2011 Walter Payton Man of the Year Award.
Birk started his career in 1998 with the Minnesota Vikings and finishes his career after his fourth season with the Baltimore Ravens.
The 36 year-old will have a lot of time on his hands now that he's done with football. A lot of people would like to see him end up as a TV or Radio announcer in the future. As for the Hall of Fame, it is unlikely he'll be elected to get it, but for his fair share of run and pass blocking through his 15 years in a league, it is worth a mention.
