Dungy met with Vick last week at the federal penitentiary in Leavenworth, Kan., where Vick is serving a 23-month sentence for bankrolling a dogfighting conspiracy.
Dungy spoke Wednesday at a workshop in Indianapolis for offenders seeking jobs. He compared Vicks situation as he nears his release from prison to theirs.
Dungy didnt discuss details of his visit with Vick, but told The Associated Press that the former Atlanta Falcons quarterback made a mistake.
Vick is to be transferred May 21 to home confinement in Hampton, Va., which is scheduled to last through July.
