Ja'Marr Chase is finally saying what everyone already knew -- Dolphins TE Mike Gesicki's got his Griddy touchdown celebration all wrong ... and the Bengals wide receiver says the guy needs to do some homework!!
Gesicki went viral recently for trying to do the fun dance that Chase and his old LSU teammate Justin Jefferson made famous ... but not necessarily nailing the vibe.
Chase joined "The Pat McAfee Show" and was asked if he had any plans of helping Gesicki with his Griddy .
