James Mikely Mantell Posey, Jr. (born January 13, 1977 in Cleveland, Ohio) is an American professional basketball player, currently a small forward for the Indiana Pacers of the NBA.
Posey attended and played basketball at Chamberlin Middle School and Chamberlin High School in Twinsburg, Ohio. He grew up with NFL cornerback Kelly Herndon who also went to Chamberlin.
Posey came to Xavier University in the 1995–96 season, but under Prop 48 rules, was ineligible, so sat out his freshman year. Posey ranks 16th on Xavier's all-time scoring list with 1,455 points and 10th on Xavier's all-time rebounding list with 801. Posey led XU in rebounding in each of his three seasons as a Musketeer. Posey earned a long list of honors while at Xavier, including the 1998 Atlantic 10 Championship "Most Outstanding Player" Award in helping XU win its first-ever A-10 Tournament Championship. Posey earned the A-10's "Sixth Man Award" twice and was named 1999 A-10 First Team and 1999 A-10 Defensive Player of the Year. He did all of that while not being a consistent starter in the Xavier lineup, almost always coming off the bench and in uncustomary fashion, Posey coming from a small mid-major university, became well sought after from several sports agents such as Bill Duffy, Andy Miller, Craig McKenzie and Mark Bartelstein. With their permission Posey allowed his interviews to be held in front of the media of the Cincinnati Enquirer.
