Depending on how long Marty is out for, and of course how well he goes against Canberra, Paseka could well be starting the next 2-3 games for Manly, at least. I hope you're right and that being picked in the starting XIII will do his confidence the world of good.
None of us want him to fail, quite the opposite in fact because it can only benefit both himself and Manly. But we'd all be a lot happier if he started using his ability and natural size advantage to full effect a lot more often than we've seen.
