Lucas: Tank Powers Offensive Line Posted Aug 17, 2006 Sometimes it's a challenge to figure out the origin of a player's nickname. D.J. Walker's "Junebug," for example. He wasn't born in June. He isn't small and shifty, like a junebug. It's just something that has stuck from childhood. And then there's Scott Lenahan. He's better known as "Tank" to his Tar Heel teammates--and there's no mystery about how he earned the moniker. (Tar Heel Blue)
