The United States does cricket? It isn't a Commonwealth country.
That doesn't matter.
'The United States does cricket? It isn't a Commonwealth country.'
Football is only Rugby with a few rule changes - the Brits invented that as well and no-one reckons we should be a commonwealth country to play that.
I can think of two things:
1. The United States is an English-speaking country? It isn't a Commonwealth country.
2. Canada doesn't do cricket? It is a Commonwealth country.
Seriously, if we look at this issue in another way, believe it or not once upon a time cricket was the premier sport in America, and in particular, New England. Of course this happened long before Babe Ruth was born.
