Because one is telling the truth and the other is using the media to push a narrative.
BB walked from Brady. Only one side is speaking a lot.
So you're saying that Bill Belichick is using the media to push a narrative, while in the same breath claiming that he is not speaking a lot. Cmon man, have some intellectual consistency. Either he is talking and pushing a narrative or he isn't, not both.
You can't be telling "the truth" when you're speaking on someone else's opinion, unless you're claiming to be psychic. No one can see into another's mind or heart, and though we can think we know what they're thinking and feeling, and can guess at it, ultimately everything is just bullshit, based on both the arrogant presumption that they think like we do and feel as we would feel, as well as misguided confidence in our knowledge of their experiences and circumstances. I don't care who you've talked to or how much you think you know what "the truth" is as far as Belichick's opinion and feelings on this, but the reality is you are not an authority on that topic. Only Belichick can be.
So no, when he says Brady was offered a contract, and declined to take it, that he wanted Brady to stay on, and every move the team made was in an effort to make things as good as they could be for Tom Brady, but ultimately they weren't as good of an option as Tampa at that time, I will choose to believe him. You may choose not to, but unless you have an iota of actual evidence, and not simply 'my feelings' and 'my truth', please stop presenting your presumptions as "facts".
