The hard way isn't too hard and doesn't require but a line of code:

 >> leagues=%w{ 1D 2D U16 U19 LR RR JNL NL}
=> ["1D", "2D", "U16", "U19", "LR", "RR", "JNL", "NL"]
 >> str="some stuff NL is chunky"
=> "some stuff NL is chunky"
 >> leagues.find_all { |league| str.include? league }
=> ["NL"]

Hope that helps.
