Does he have the required game management skills? Agree that he likes the ball in his hands but seems more an eyes up type to player - dare I say “Brooksesque”?Sullivan isn't playing 7 though, he is playing 6. He is a better 7, more on the ball and roving around the ruck rather then on an edge as a 6.
I would drop Sezer for Galvin and move Sullivan to 7.
