Q: Question: How long did the powerhouse coach work at St. Thomas Aquinas High School? Passage:A native of Miami, Florida, Joyner originally attended Southwest Miami High School, where he played three seasons on the varsity football team at linebacker and defensive back as well as wide receiver and kick returner. As a sophomore, he had more than 100 tackles and also accounted for more than 1,000 yards on offense. In his junior year, he recorded 112 tackles, four sacks and an interception. He then decided to transfer to St. Thomas Aquinas High School in Fort Lauderdale, Florida, a private school and football powerhouse coached by George Smith. Featuring talented running backs Giovani Bernard and James White, St. Thomas Aquinas went undefeated through the season, extending a win-streak that began in 2007 to 37 wins, until losing 28–20 to Manatee High School in a Class 5A state semifinal at Hawkins Stadium in Bradenton, Florida. For the season, Joyner contributed as a shut-down cornerback, recording only 14 tackles (12 solo) as opponents stayed away from his side of the field. He also starred on special teams, as he averaged 39.6 yards per return and managed to return three kickoffs for scores. On offense, he recorded 1,090 all-purpose yards on just 79 touches, scoring four rushing and four receiving touchdowns. His impact on the defensive side, however, earned him the National Defensive Player of the Year award by USA Today.
