N. D. Kalu

N. D. Kalu's NFL career began in 1997 when he became a defensive end for the Philadelphia Eagles. He left the following year to join the Washington Redskins, only to return to the Eagles in 2001 and then join the Houston Texans in 2006, where he stayed until the end of his professional career in 2008.

He was already thinking of life after his sports career before it was over, and he founded the Kalu Group real estate company in 2007 as a result. According to its official website, the company "invests and operates in the acquisition, rehabilitation, management and sale of properties in both Texas and Pennsylvania."
