As for boras, he is just trying to tout his clients as the best baseball players available on the market. If he was my agent, I'd expect the same, and he is excellent at what he does.
To us (and probably a lot of baseball executives) his posturing sounds ridiculous, but he handles a number of baseball's elite talent so you have to deal with the man.
Just figure out the value you are willing to pay for a player, and make the best offer you can.
