re: World's Fastest Rugby Player? (Video)

is the pitch the same size in sevens as in the 15s? I know for a lot of people more scoring = more fun, but as shown by what Isles can do (and I'm sure there are others like him) it just seems a lot less...Rugby-ish? if that makes any sense. I know I'm new to this sport, but it just seems like there is a lot more skill and strategy for 15s over 7s not just spread the field and get it to the uber fast guy.
