After naming their team’s home field after their star graduate, Point Loma High School invited ex-Major League Baseball pitcher David Wells to become their assistant coach. And the man nicknamed Boomer, who played for the Toronto Blue Jays and New York Yankees, later made the move up to head coach in 2014.
17. Andre Rison
Andre Rison won the 1996 Super Bowl with the Green Bay Packers, notched up touchdowns with seven different sides to break an NFL record and achieved the rare feat of winning professional championships in both Canada and the U.S. But after getting into financial difficulty post-retirement, Rison was forced to take an assistant coaching position at an Ann Arbor high school to make ends meet.
16. Ricardo Silva
While the likes of Rison have returned to high school to offer their words of wisdom on the football field, Ricardo Silva decided to head straight for the classroom instead. The ex-Detroit Lions safety now teaches geometry at a Washington high school, having signed up to the Teach for America program. In 2015, moreover, he told CNN that the profession is far more difficult than anything he experienced in the NFL.
