I am sure we would have to pay peak value for a guy like Robert, so probably something similar to what we gave up for Yeli. 1 high end prospect, 2 borderline top 100 pieces, and a mid-level 3rd piece.
That would be like Black/Mis, Frelick/Mitchell/Weimer, Gasser/CarRod/Lara, and like Blalock. So like Black, Frelick, Gasser, and Blalock would be to much but Black, Weimer, CarRod, and Blalock I would consider
I like Robert a lot but his injury problems and lower obp/higher k rates make a trade a ginormous risk. If we are giving up that end of capital I guess I would rather go after Isaac Paredas, Christian Javier, Jesus Luzardo, or other top end talent that might end up available come July
