Oh come on..
Joyce lost credibility to me since the bullshit he said about that NBA player coming out. Also, this is from an article talking about another interview where Joyce said what ALLEGEDLY Yuri said... ppff.. And obviously Maria is stubborn, I'm sure she is, just like many sport stars I think, so what the difference between him and Hogstedt be? Like Crimewave said, he wasn't Maria's coach before Wim 2004 and it seems to me he didn't do much more for her to beat Serena than what Hogstedt did. Serena is the superior player and that's pretty much it.
Like I said on GM, to sum it up: go home Joyce, you're drunk.
