Sorry but this part was quite funny to read and I thought it could get lost in translation, although many people will probably understand it given the context. Lanzar mandarinas (to shoot / to throw tangerines) is an expression popularized by a famous (and unfortunately deceased) Spanish broadcaster, and it would be the equivalent to shooting bricks in English.
Now, Elfront, don't get too worked up because of what you read here or on any other basketball forum. Most fans can't help looking for a scapegoat when things are not going as they expected (regardless of whether those expectations were fair or not), and the easiest guy to root against is the one who's not that good at shooting, because for most of those fans it's more obvious and easier to assess than defense, leadership, intangibles or just being good at running an offense. You can bring a lot of those things and even do it consistently, but if you're not shooting well it's not gonna go unnoticed, and those same fans will even talk about how the rest of your game isn't that good either, or it's just not as important for the team. You just need to learn to live with it, don't pay attention to the haters, and if you still have a hard time reading them then the ignore list is your friend. There's one in every forum and it's pretty useful to avoid wasting time on trolls, haters or openly dumb (or merely ignorant) posters who would just feel naked and empty without their preferred narratives, so they just keep repeating them over and over.
As for Ricky's comments, I understand them, no player likes being offered to a different team when he's happy with his situation there and is confident the team can reach its goals, but that's the NBA for you. He'll move on right away and just give his all on the court as usual. And when July comes, he can look for a new home and find a situation where he doesn't have to go through the same experience next season. It's not like he fits the Jazz offense perfectly, nor viceversa, so it'll probably be for the best anyway.
