Baptiste enrolled at Creighton University with a full athletic scholarship to play basketball for the Bluejays.[3] He was sometimes listed as 6-foot-10-inch (2.08 m) but claimed this height was fabricated to "psych out" other teams and he was actually only 6-foot-7-inch (2.01 m).[3]
Baptiste toured with the Olympic development team before his sophomore season.[4] Baptiste began to experiment with drugs during his sophomore season as part of an "innocent curiosity".[3] He developed an addiction to heroin and claimed that he played while high his entire junior season, which caused him to lose weight.[1] A decline in his playing performance heightened the suspicions of head coach Eddie Sutton but physicals were unsuccessful in finding anything.[1] Baptiste's interest in his college classes declined and he was assisted with his grades by Creighton until he dropped out of university two weeks after his junior season ended.[1][3] Sutton lamented in 1989 that he "probably will never get another ballplayer with that much ability" as Baptiste.[5]
Professional career
Baptiste was made eligible for the 1971 NBA draft as part of a hardship round and was considered as a "glamour name".[6] He was selected by the Golden State Warriors and signed a $450,000 contract.[3] Baptiste was suspended in training camp before the 1971–72 NBA season for being "out of condition" and subsequently lost most of his contracted money.[3][7] The Warriors sent Baptiste to several drug rehabilitation programs and kept him on their suspended list until he was placed on waivers on January 15, 1973.[3]
