Over the course of a three-month investigation, four sources with intimate knowledge of the Syracuse men’s basketball program told Yahoo! Sports at least 10 players since 2001 have tested positive for a banned recreational substance or substances. The sources said all 10 of those players were allowed to practice and play at times when they should have been suspended by the athletic department, including instances when some players may not have known of their own ineligibility. The four sources said Syracuse violated its drug policy in at least two areas: failing to properly count positive tests; and playing ineligible players after they should have been subject to suspension.
