Take a gander at what's happening in SD to see how quickly things can change. 66-96 in 2018 and 2 games over .500 this year. Or the Braves in 2017 v. the Braves in 2018 and 2019. Both teams have added young talent to a group of existing pieces and when you break it down, the likes of Vlady, Bo, Jansen, Biggio, Pearson, Murphy, Thornton + payroll flexibility is fairly comparable to the pieces those teams have added.
I'm not saying it's a done deal, but things can change quickly.
