Win the championship, trade the old guy (Zobrist) high, or keep him as your super sub.
Pray Heyward takes player option.
If not, then at that time trade Soler.
Russell, Bryant, Rizzo, Baez, contreras, Arrieta,
All appear to be an untradable core
Soler, Schwarber, Almora,
Are right there but I think the outfield log jam, needs, play and injuries will eventually determine who stays. The trick is selling high but still choosing right.
I repeat...Epstein can't plan RF long term until Heyward options. The Yankees may stay firm until deadline, then offer Soler for Miller. I think he is just gone because he has value and no spot.
He will got hot and get traded. It's hard to gauge what Scezur, coghlin, and prospects may be able to bring.
I hope the Cubs keep them all. I fear they might be getting too comfortable since every prospect keeps coming up all star.
