The 1986–87 St. John's Redmen basketball team represented St. John's University during the 1986–87 NCAA Division I men's basketball season. The team was coached by Lou Carnesecca in his nineteenth year at the school. St. John's home games are played at Alumni Hall and Madison Square Garden and the team is a member of the Big East Conference.
Carnesecca coached the same team for at least nearly two decades.
The team was coached by Lou Carnesecca in his nineteenth year at the school, but the text doesn't say he was the coach all those years [he might have been asst. coach or even a player, for instance]. The model made an assumption from the wording of the sentence.
