Well...the more I read Rasmus' quote, the more I think it isn't that big of a deal. That looks taken out of context. I mean... If I'm Arroyo, and the guy is saying that I'm throwing slop. Well... I would just be laughing because he couldn't hit it. I'd say... "I'll serve you more slop next time". lol I wouldn't be mad about it though.
It's professional disrespect. A guy beats you, you tip your cap. Period. Rasmus has 1 year in the league, right? Clearly, he's got a little learning to do.
I doubt Arroyo lets it bother him, considering the source.
