I like Preller. Frankly the league needs 2-3 Prellers to keep all the Jeds on track.
But yeah, the window probably closed for them last night. If you assume they keep their payroll flat, they have ~$40M to replace quite a bit heading out the door in FA. Namely Cease, King, Arraez, and Suarez. If WC3 is as uninspiring next year as it was this year, Maybe AJ can keep enough plates spinning for one more go? But we're definitely near the end. And with the farm and the payroll bloat it's probably not a quick lay down for a year and come back good as new situation.
