Robert Griffin III and Brady Quinn are going at it ... the two former NFL quarterbacks were in a heated exchange on social media Thursday after the former Notre Dame signal caller criticized Ohio State QB and top draft prospect CJ Stroud for allegedly missing Peyton Manning's football camp.
RG3 clapped back at Quinn, who on Wednesday said the Buckeyes standout "ghosted" the Manning Passing Academy the night before previously committing to attend the camp.
Griffin was clearly pissed Quinn shared the unsubstantiated story, and he fired off a tweet letting Bradfy know as much.
