Rush was drafted in the ABA in 2000 by the Kansas City Knights. He was traded before the start of the season to the Los Angeles Stars, where he played the 2000–2001 season.[8][9] He entered into rehab for alcoholism in 2001. He was the final cut of the Seattle SuperSonics of the National Basketball Association during their 2001 training camp.[10] He played 14 games for the Roanoke Dazzle in the D-League and averaged just 1.8 points before being granted his unconditional release in December 2001.[9][10] He was signed to the Knights' practice squad in January 2002 before being cut in February for missing practice.[10][11] He went into rehab again and retired from basketball that year.[6] Rush accepted a job as freshman girls B-team basketball coach at Blue Valley Northwest High School in 2006.[12] He was employed at a public relations firm in 2007 while finishing college.[13]
He played high school basketball at The Pembroke Hill School, leading the team to three state championships. The state titles were eventually stripped after AAU Coach Myron Piggie pleaded guilty to a conspiracy charge for paying $35,500 to five high school players on his Kansas City-based team from 1996 to 1998. The players, aside from JaRon and his younger brother Kareem, were Corey Maggette, Korleone Young and Andre Williams.[14]
Rush won the James A. DiRenna Award as the best basketball player in the Kansas City metro area, winning it outright as a sophomore and junior, and sharing the award with Victor Williams of Wyandotte High School (and later Oklahoma State) as a senior.
His final play in high school was a windmill dunk which broke the backboard.[15]
Personal
Rush's younger brothers Kareem and Brandon are also professional basketball players. With ex-girlfriend Sarah Hofstra, he had a son, Shea, who was born during his senior year in high school. In 2013, Shea made the basketball team as a high school freshman at The Barstow School in Kansas City. Rush, who is living in Kansas City, meets with his son regularly and they enjoy playing basketball together.[16] His son committed to play for North Carolina and head coach Roy Williams in 2016.
