Successfully manipulating the politics between owners is just as important a factor in winning fantasy baseball leagues as everything else. If releasing negative press against a competitor's players can hamper his trading efforts, I say go for it.
Thank you very much. I happen to be in this manager's league, and I am in fact the manager that posted the stuff. You wanna know why? Because he did the same thing to me when I trade to trade Armando Benitez earlier this season. He did the exact same thing to me making a big post and everything. I am meerly returning the favor to him. Secondly, I'd like to quote another user:
From now on you are obligated to post any injury or trade rumor related news about any player on the team of the guy who posted that crap. And sully that owner's reputation any way you can. What a douchebag.
I doubt you even know what a douchebag is, but if it sounds cool, why not use it, eh? Anyway, it's pretty childish to use it like this in a situation that doesn't even apply.
Just wanted to clarify this that the other owner was the one who in fact started out this "injury posting thing" against my team. Frankly, I don't see a problem with what he did or what I'm doing, but I felt I needed to return him the favor in this case.
