I know its fun to talk in certainties. But what are the odds of this if everything you suggest is done. And what is your definition of dominant force.
TBH, I'm not sure about 2018.. but definitely 2019 and dominant force as in like Cubs, cheap young players in all positions with veterans we can get (from big 2018 FA class).
In a situation we trade all three, we would get a massive return back for the three players. I'm just going to make a mock trade to the RS in which they would be receive all three prospects bc they can use some pitching help, 1B help, and bullpen help (always)...
We would in return receive a package in value to: Moncada(Freeman gets), Devers (Freeman gets), Benintendi(Teheran gets), Swihart(Teheran/Vizcaino gets) and Kopech (Freeman/Vizcaino gets)
...That trade won't happen but we could get that type of a haul (obviously in separate trade though bc nobody would trade that much talent) for the three players...and we draft an elite bat in the 2016 draft, the 2018/2019 roster could look like (with just the RS trade as a base):
1B Devers
2B Albies
3B Moncada
SS Swanson
C Swihart/Herbert/Morales
OF Benintendi, Lewis, Smith/Davidson/Acuna(?)/other
SP Newcomb/Sims/Wisler/Touki/Soroka/Fried/Sims/Ellis/Blair/others whoever doesn't bust...
That's a pretty explosive roster top to bottom and I would expect it to be a championship caliber team..
Like I said, if we do trade with the RS, we won't be getting their top 3 prospects and Swihart, but in terms of value, we could get that much back for Tehran, Vizcaino, and Freeman IMO and that would again IMO help us be contenders by 2018/2019.... I'm not the GM though, and alot can change and we can just see how the trade deadline plays out...
