The Titans are taking a huge risk playing Hayne in this game, which they've indicated they will do. No doubt a cameo off the bench as he will be neither match fit nor versed in the team's plays. They are looking for an instant reward at the gate while putting their finals chances at serious risk. Hayne on the bench will mean a bench forward short. This match is almost a semi-final and they can ill afford to give the opposition such a leg up.
Hayne might make one of his trademark length of the field runs, beating the entire opposition team, and making a goose of TheFrog and many others. But I consider that unlikely in this game. More likely the Warriors will try to smash him, legally of course.
I'm tipping the Warriors because the Titans are giving them a free kick in order to boost the crowd, ie revenue. I just hope the Titans don't get any free rides from the refs in this game. The implications would be appalling.
