Aaron Rodgers is going all-in on his Nicolas Cage obsession -- the superstar quarterback now has a bust of the actor's head in his locker ... and he showed it off to reporters on Tuesday.
38-year-old Rodgers was all smiles as he brought the Cage head down from the top shelf of his changing space to give a closer look ... chatting it up as folks in the crowd got their jokes off.
Some said the bust doesn't really resemble Cage ... but we gotta admit -- it looks pretty spot-on.
