Rivers, a 6-4 point guard known for his defensive ability, played the past two seasons at Georgetown. He played in all 34 of the Hoyas’ games last year, averaging 2.5 points, 2.4 rebounds, one assist and one turnover in 18.6 minutes per game. He will sit out next season per NCAA rules and have two years of eligibility remaining. Rivers is the seventh player in Indiana’s incoming class, and the fifth brought in by new coach Tom Crean since being hired in early April. Crean knows the Rivers family well; Doc Rivers, Jeremiah’s father and the coach of the Boston Celtics, starred at Marquette and was close to the program during Crean’s tenure with the Golden Eagles.
