While the Knicks have been focused on acquiring D’Angelo Russell as they eye point guards before Thursday’s 3 p.m. NBA trade deadline, the Knicks also at some point made an inquiry into Pacers playmaker Aaron Holiday, the younger brother of Jrue and Justin. Holiday, 23, is in his second season. After a modest rookie year, he’s played in 47 games, made 19 starts and in 23 minutes per game is averaging 10.2 points and 3.5 assists.
