Watch: Rugby's tallest ever players

Professional rugby players are often viewed as giants among men, in this context the second row become giants among giants. This makes compiling a list of the world's tallest ever players a 'tall' order to say the least.

There is a mantra thrown around habitually in rugby, that it is a game for all shapes and sizes, which is becoming less and less true with every passing season. Second row however has long been a niche position, never one for the faint-hearted or those of us who are vertically challenged.

The margins were so tight that we had to factor in weight as a tiebreaker to decide certain positions. Ultimately as Al Pacino would say, it came down to inches and when we added up all those inches that was the difference between winning and losing.
