He seems heavily influenced by black sports star culture in America...i.e. forget humility, sell yourself constantly and basically be the big swinging dick. Its a confidence thing and while it can be humorous, it can rile some up the wrong way.
The thing is though...he talks a big game and plays an even bigger one. In a rep environment, you want extremely confident people in there revving the rest up. NSW has plenty that do this - To'o, Crichton, Mitchell, Lomax, Cleary, Moses, Barnett, Martin, Crichton, Watson, Leniu, Young...pretty much all of them. Usually Luai is there doing it as well. There is no way in the world that May wouldnt fit in with this group. He suits that company way more than he does the Wests Tigers and look at his results this year....best forward in the comp and arguably the best player overall - certainly top 3.
Leaving him out of Origin is shameful and smacking of bias and seething politics.
