If Haas does play I'm expecting he's going to have a massive game, make huge Metres and have bulk tackles. All so he can show off to potential suitors how good he is and what he can do, blah, blah, blah.
It makes me sick because while he's trialing for other teams out there he's going to affect the rest of the team and it's cohesion while he treats the game more like a try out rather than a genuine competition. I don't see him passing, offloading or doing anything that benefits the team more than it will Benefit him. Expect him to take runs when he shouldn't have the ball and expect him to overplay his hand.
