My name's Frank and I'm one of the tallest guys in my leagues so a lot of people call me Tank, some people call me FT for short since one of the guys started saying that, a lot of people followed.
Although when I first played in my first league game, one of the guys thought FT stood for freight train because I was big, could skate fast, but couldn't turn well or stop well.
He kept calling me that until he stopped playing in the league and was the only one that called me that though.
