Jameel Cook -- a former Super Bowl champ with the Bucs -- was just convicted of stealing over $100K from an NFL player trust fund ... and prosecutors raked him over the coals afterward!!!
"He stole from the very fund his fellow former players depend on for help," Harris County District Attorney Kim Ogg said ... "And he has now fallen from professional football glory to the ranks of felons."
As we previously reported ... the ex-Tampa Bay FB was busted back in September after officials say he stole money from the Gene Upshaw NFL Player Plan -- a fund set up to benefit ex-players.
