Hey, I'm in a 12 Team dynasty league with no salaries and a 7 spot MiLB roster. Looking at trading Melky Cabrera and my team is attempting to build toward the future. My roster is as follows:

Hitters-Jesus Montero, Kendrys Morales, Neil Walker, Kyle Seager, Troy Tulowitzki, Zack Cozart, Eric Hosmer, Alex Gordon, Melky Cabrera, Justin Upton, Jason Heyward, Shin-Soo Choo, Chris Young, Lance Berkman, Devin Mesoraco, Pedro Alvarez, Colby Rasmus, Jayson Werth

Pitchers-Trevor Cahill, Strasburg, Josh Johnson, Jordan Zimmermann, Chris Sale, Kenley Jansen, Pedro Strop, Jered Weaver, and Drew Storen.

MiLB: Jarred Cosart, Jose Fernandez, Anthony Rendon, Jake Marisnick, Matt Harvey, Javier Baez, George Springer

I've tried to stockpile hitters that could potentially breakout and become stars. I was offered Melky Cabrera for Aroldis Chapman. Think I take it? Any advice on molding my team?

Thanks for the help!
