After six seasons in Kansas City in which he shined on the field, but had numerous off-the-field problems, Carter signed a four-year, 22.8 million-dollar contract with the Broncos in 1999, making him the NFL's highest-paid defensive back. After a poor year, Carter was suspended for the entire 2000 season due to a fourth substance abuse violation before being released during the 2001 season. He then played for the Vikings, Saints and Ravens before retiring after the 2005 season.
Upon retirement, Carter started a non-profit organization to assist young men and women from making the same mistakes that he made. The Olivia Carter Foundation based in Dallas/Ft.Worth Texas and its vision is "To empower and enhance the lives of today's youth by giving them a voice of hope"
