1. No, we all dont know that its not happening. Its unlikely to happen, but that doesnt mean its a done deal that its not.
2. Because the posters who said it, who you are specifically referring to, in this case 5 goldgloves and Duranistheman, I look forward to their posts, and its good to see others here push back on the whole we should be thankful for what we get boot licking narrative or the money isnt correlated to success fallacy
3. Because of the people saying "dont talk about what we deserve or what we should get or what we could get, instead work within the assumption that the offensive improvements is going to revolve around casas and yoshida" are more annoying than the people you are shushing.
4. Because I believe that not saying what we could get, what we should get lets ownership and management off the hook, and we're just not going to lick boots
5. Finally, because of the people in the "dont expect much camp, most of them are also in the camp of "fans are greedy, praise be our billionaire overlords. TY for our scraps and cellphones" and its pathetic. You are trying to manage your own expectations and prevent yourself from disappointment. I see a distinction between that and the people saying "Henry deserves his third yacht!!!! And I wubbbbb Casas and Yoshida and dont want to see their positions threatened"
