What?'s his defense? Baltimore Ravens linebacker Ray Lewis -- who earned $7.2 million in 2011 -- couldn't spare a dime of it for his own charity, The Post has learned. Lewis, who is playing his last game in tonight's Super Bowl, set up two charities to polish his image after pleading guilty to obstruction of justice in 2000 in connection with a double homicide in Atlanta that year. He started the Ray Lewis Foundation in 2002, but the group lost its IRS tax-exempt status because it failed to file tax returns for three years. He opened the similarly named Ray Lewis Family Foundation in 2010.
