6 Alec’s Attack on Long John “He seems to have the Indian sign on me.” -- Long John “It is significant that, in making his challenge, Alec selected Long John instead of Doc, Danny, or Mike. It was not that Long John's bowling ability was uncertain. His average was about the same as that of Doc or Danny and better than that of Mike. As a member of the top group but not a leader in his own right, it was his social position that was vulnerable.” – Whyte
