They interviewed him after the game
He laughed it off and said he was pointing at Jimmy Dymock who said he wasn’t running hard enough at half time and had to prove him wrong. He wasn’t aiming at Flanagan (apparently)
Total media beat up.
To add context Fafita scored a try in the 69th minute then pointed at the coaches box and was screaming profanities ... commentators, especially Alexander were assuming he was screaming at Flanagan
