Long established himself quickly with a Detroit program that would produce an unprecedented run during his time with the Titans (1974–1978).

UD advanced to the 1977 NCAA Division I Basketball Tournament in his junior year, defeating Middle Tennessee in the first round before losing to Michigan in the Sweet 16 86–81 to end a stellar season, finishing #12 in the polls.

Long was the original backcourt partner to point guard Isiah Thomas before Joe Dumars was drafted.

During his time with the Pistons, Long would also play alongside University of Detroit teammates Duerod, Boyd and Tyler.

On December 13, 1983, Long scored 41 points, recorded eight assists, and grabbed six rebounds during a 186–184 triple overtime win over the Denver Nuggets.
