Is this even up for discussion?
Harris is the man. Our pack leader. He has long hair. He is Jesus.
If you mean "pack leader" as in, in-your-face, prepared-to-risk-a-penalty-to-rark-people-up, not sure if we've got that at present. I know getting in your own player's faces when they're not delivering what's required is also part of the job description, but you can't ignore that first part.
Jazz offered that, but there's a line in playing that role and he crossed it a few times.
Although, to be fair, being a Warrior might put a spotlight on him that wouldn't be there if he wasn't a Warrior...
Let's not forget that Steve Price was regarded as rather mouthy - "most difficult captain to deal with" was the official terminology, IIRC - by the referees
when he was New Zealand Warriors captain. This came out in a Rugby League Week survey of NRL match officials in 2009.
So the Warriors signing a renowned "pack leader" from Australia didn't work/won't work.
All I'm saying is all of us who want a pack leader may need to tone down our dreams of what that pack leader can do without attracting the disapproving whistles of NRL officials.
