Everybody loves a good nickname, especially pro athletes, who will at the very least throw a "y" on the end of a teammate's last name and pass it off as an alternative moniker. The Ravens have had some good ones over the years. Usually, players are gifted a nickname by someone else, like when Frank "The Tank" Walker dubbed Jim Leonard "White Lightning." Other times, they give themselves one like "Chocolate Therapy," which belongs to Bernard Pollard. In this week's Five for Friday, Matt Vensel ranks the all-time best Ravens nicknames.
