Well, as far as Barcelona is concerned I think they definitely have the advantage because this is only a pre-season game so Kobe has absolutely no incentive to want to try and risk getting injured by a European team before the season actually starts.
I am actually rooting for the Lakers to beat Barca in only this game even though I support Barcelona's futbol club solely because I despise Real Madrid and Cristiano Ronaldo and currently Real is leading them in the La Liga standings.
It would actually be kind of amusing if Barca played a game against the Boston Celtics because I don't think they would even stand a chance vs our squad; remember that basketball is a much bigger deal in the States than it is over in Spain, and the Spanish are absolutely crazy about their futbol.
We'll see what goes down in the 4th quarter, maybe the Lakers will actually win their first pre-season game? I know that it took Kobe 1.5 full games before actually scoring a 'field-goal', and I'm not talking about 'soccer'.
