Bo was looking for a long term contract, and long term contracts usually have lower AAV. We know that the Phillies offered $200M for 7 years, and I wouldn't be surprised to learn that the Jays offered similar. This is what Bo had told people he was looking for.
He then turned around and signed a 3 year high AAV deal. He just decided to pivot and play a totally different game than the one he'd told everyone, without telling the other teams he'd engaged with. I don't think we can blame anyone for not making better offers when he seems to have made a very sudden change in his decision making process.
