Johnny Manziel -- Partying with Drake ... 's Dad (PHOTOS)

Johnny Manziel went from 0 to 100 real quick at Coachella ... partying with Drake's dad!!

Check out these pics of Dennis Graham -- who was CRUSHING IT at Coachella this weekend ... not only hangin' with Manziel ... but also partying with Philadelphia 76ers prodigies Nerlens Noel and Joel Embiid.

No word on what he talked to Manziel and Noel about ... but with all of their off-the-field/court drama, maybe some good ol' fashioned fatherly advice?

It's possible ... but wait a sec, 'cause now he's with APOLLONIA!!!!

Drake's dad is a frickin' baller.
