Johnny Manziel Wants To Be A Bronco

Johnny Manziel is keeping the Broncos rumor-mill churning.

The former Cleveland QB was leaving The Nice Guy in WeHo Friday night when our photog opened the door for Johnny, to shoot down the rumor or embrace it ... he did the latter.

Johnny has big love for his former college teammate Von Miller .... and that seems to be a driving force for him.

BTW, the night was still young, so Johnny went down the road a piece and partied at Henry's, where he took a bottle of Ace of Spades to the face.
