Mr. Basketball USA, formerly known as the ESPN RISE National Player of the Year and EA SPORTS National Player of the Year, is an award presented to the United States boys' high school basketball national player of the year by Ballislife.com. Before 1996, retroactive recognition was determined for honorees going back to 1955's selectee Wilt Chamberlain, determined by National High School Hall of Fame member Doug Huff, who has been a McDonald's All-American Game selection committee member since the game's inception, CalHiSports.com Editor Mark Tennis and Ballislife.com National Editor Ronnie Flores. From 1996–2002 the selections were made by Student Sports and from 2003–2009 by EA Sports. From 2010–2012 the award was determined by ESPN HS until the award was taken over and executed by Flores in 2013 after his tenure with ESPN ended.
