#10. Ben Wallace: Basketball
It is hard to imagine that scouts didn´t rate Ben Wallace highly in the beginning. Despite possessing a towering frame of 6´9¨, he was still considered too small to occupy the center position. However, after signing as an undrafted free agent in 1996, Ben Wallace showed his worth and won 4 NBA Defensive Player of the Year Awards and made the All-Star team 4 times. At his prime, he also helped the Detroit Pistons to an NBA championship. Ben Wallace truly proved his worth to the critics and naysayers. The Pistons did him a great honor by retiring his jersey number 3 in 2016.
