premise: The Lancashire League is a competitive league of local cricket clubs drawn from the small to middle-sized mill towns, mainly but not exclusively, of East Lancashire. Its real importance is probably due to the history of employing professional players of international standing to play in the League.
hypothesis: Professional players of international standing can only play in the Lancashire League if they were born within 50 miles of East Lancashire
reason: The statement does not indicate there is any residency requirements for the East Lancashire League, but a lot of the keywords in my sentence matched the stated sentence and it could theoretically make sense
