It's already happened. Chris Davis was one such guy when he signed. Forget exactly where his deal ranked at the time but it was first page. Tejada wasn't too far off either.
Tejada's 6 year $72M deal in 2003 would be $125M today.
Davis's 7 year $161M deal in 2016 (not factoring the deferred) would be $214M today.
The very best players today are going to command how much more than those deals?
The Dodgers (when factoring in luxury tax) are spending over $500M on their roster this year.
My guess, is that if the best player / one of the true very best players are available in FA... that the O's aren't going to play at the levels necessary.
That doesn't mean I don't think they aren't going to spend money, I do.
Just not at the top top of the market.
