The Miami Dolphins selected Hill in the first round, with the 23rd overall selection, of the 1991 NFL Draft. Hill missed four weeks of training camp in a contract dispute, before he signed with the Dolphins, reportedly for $2 million. After the first game of the 1991 season, with Dolphins coachDon Shula believing that Hill was not ready to play, the Dolphins traded Hill to the Phoenix Cardinals for a first round pick in the 1992 NFL Draft. Hill caught 58 passes for 861 yards and three touchdowns in 1991, had 43 receptions for 495 yards in 1992, and recorded 35 receptions for 519 yards with four touchdowns in 1993. He played with the Cardinals through the 1994 season, and then returned to Miami for the 1995 and 1996 seasons. He spent the 1997 season with the New Orleans Saints. He led the Saints with 55 receptions for 761 yards. He signed with the Chicago Bears for the 1998 season, but did not make the team.
Hill was interviewed about his time at the University of Miami for the documentary The U, which premiered December 12, 2009 on ESPN.
