"Luck is the residue of design" to that I would add intelligence and hard work. Sometimes your good fortune is due to other's mistakes.
Okafor played for Josh Pastner's father's AAU club; there was some friction there. Okafor looked hard at Stanford, but for some reason
they weren't that interested. Houston at that time was an open recruiting area. UConn got a foothold in the Metro area at Strake Jesuit.
There was a top guard UConn was interested in. The second choice was a near top 50 player who UConn got; he was a bust. However, while on the recruiting trips the only member of Perno's staff retained by Calhoun noticed an unheralded big man who had never scored 20 points in a game at any level. Jake Voskhul was a real find. The top 50 kid failed at UConn; and later failed at Vanderbilt. He ended up at an NAIA school.
During his first iteration as a UConn assistant, a current UConn assistant, was tasked with watching Taliek Brown all over the country. Taliek played AAU ball in Houston, not for the Pastner team. So UConn had a little some purchase in the Houston area.
There was a more promising big in the Houston area, who ended up at Baylor in the greatest trainwreck in college basketball history.
He later transferred to Mississippi State where he was a top player, second team All American.
Okafor blew up his senior year; it was down to UConn and Vanderbilt. For some reason the Vandy visit didn't go particularly well.
Several UConn staff members convinced Calhoun to watch Okafor in an all star game in Pittsburg. He met Calhoun's eye test. Coach Calhoun could be quite effective with certain types of parents; he sold the family on UConn's ability to provide Emeka with a quality education.
Actually there is more to this one story than I am telling here, but Okafor was a major success beginning in his first game at UConn.
Is it serendipitous that what limited Okafor in the NBA has been his back problems. Don't get me started on Calhoun's relations with
AAU programs; UConn the premier New England college program during Calhoun's tenure wasn't able to get a single recruit from BABC until Jeff Adrien.
Okafor's recruitment started with Calhoun's decision to retain Howie Dikerman as an assistant.
