Honestly, people are just popping their tops for no reason.
Yeah, it doesn't look good that Hoffman is in those pictures but he's not the one posting them. The Bulldogs players obviously like him and they want him to come to Belmore which is why he's in those pictures. He's not wearing a bulldogs jersey or posing with the flag by himself. He's not going to tell his mates "come on, guys. don't post those pictures with me".
So far anything Hoffman has said anything directly it's only been indicating that he's coming back and he still wants to play at fullback, a little bit of ambition is good.
