Sorry Tony Romo, ya ain't Terrell Owens quarterback anymore ... at least not starting QB ... 'cause the ex-Cowboys star says the team would be CRAZY to bench Dak Prescott.
Shocking ... if ya remember the viral video from '08. T.O. -- rockin' shades, cried talking about Romo -- dropping the infamous, "that's my quarterback" line after Dallas lost a playoff game.
So, when we saw T.O. in Venice Beach yesterday ... we asked him to weigh-in on the hottest debate in the NFL ... who should start as signal caller for the Boys.
