It's always follow the money but with this clown it's follow his former clients. Nimmo (a former client) is projected to make $1.7M in arbitration this year. No reason to trade him now. Michael Conforto (Boras client) is projected to make $9.2M this year with another arb eligible year in 2021. That's a significant savings.
They can't rat hole these "assets" forever. Not every minor leaguer is going to be an everyday big leaguer so getting value for the ones they don't see helping the big league club is a smart move. They better move soon because some of them are depreciating quickly.
interesting article about this trade on Fangraphs. It seems Urias made a swing change to add some power that didn't work. His swing and miss went up but his exit velocity did not. Too much soft contact. Longenhagen is a fan so he's still holding out hope for some physical projection at 22 yrs old. SS is the place to play a low impact bat but there's a question if he can be league average there. The Brewers are light up the middle but this looks to be a very risky move.
He made a big jump but damn does Preller love his OF's. Manuel Margot, Trent Grisham, Hunter Renfroe, Wil Myers, Franchy Cordero, Josh Naylor and he traded for Taylor Trammell earlier this year. Preller would field an entire team of OF's if he could.
