Yes, Luke Lewis is a genuine professional. I hung out with him one year prior to SOO (the first year Aku played) with the other NSW players at a private gig and needless to say everyone was pretty loose. Luke however was dead sober and had a glass of water with him and at one point noticed that I wasn't drinking either and commented on it. He ended up sitting down with me and ended up having a good conversation and he mentioned how all his life he's known all he ever wanted to do was play football and that he's never been a drinker as he feels it could be detrimental to his footy. Anyway, great bloke, really genuine person who is incredibly focused and just the ultimate professional. He'd be a great influence on our kids.
I got to know Birdy pretty well and he's a great guy but obviously he's loose. At least he was 2-3 years ago, maybe he's settled down now.
In short, either would be a great signing but I'd prefer Luke Lewis for his professionalism and influence.
