That may be true but rumor has it that there were other "interesting" considerations from that West Coast school that may have helped greatly in the decision.
Professor Jack Clarke who has been at St. John's since the 50's told me personally that the climate at St. John's at the time may have been more interested in the health of Joe Lapchick than Alcindor. They would have had to change the rule of mandatory retirement and they would have had to have a meeting with Lapchick , Looie , Alcindor and his parents about transitioning the stewardship to Looie. This may have satisfied all involved as Joe died in 1970 a mere four years later. Ned Irish from the Garden would have to be involved, finding a job for Alcindor's father. This would allow a big picture to be presented to all parties regarding how large this was going to be. Finally they would have to get prominent black leaders to preach the values of NY and St. John's, much like UCLA did with Ralph Bunche and Jackie Robinson showering Alcindor with the virtues of UCLA. Not an easy task but certainly by today's standards very doable.
