As much as it sucks for fans, AA likely made the right call yesterday.
I mentioned several days ago that there had been reports mentioning that we can pretty much expect that all but the richest teams are likely going to be looking to cut payroll by as much as 20%-30% this winter. Jon Daniels admitted as much in an interview yesterday. AA gave himself lots of flexibility by not adding any future salary since he "sat on his hands" at the deadline. He's not going to have to make any tough decisions at this point - just let Melancon, Greene, Hamels, Flowers, and Markakis become free-agents and you've dropped 30.8% of your present payroll. You have in-house replacements for all those guys in Smith, Martin, Soroka, Contreras, and Waters. You can save another $3 million if Pache replaces Duvall, and $1 million plus if Shewmake replaces Hechavarria and Culberson and $1 million plus if Weigel/Ynoa/etc. replaces Luke Jackson.
As unlikely as it is that Riley's going to keep this up moving forward, there's at least a little hope. Ozuna's not going to get $18 million per from anyone this winter with everyone looking to cut costs, and there are likely going to be quite a few bargains out there. You spend his money bringing him back or on another right-handed DH/1B/OF bat and plugging holes and you've essentially brought this same team back while cutting salaries by over 20% even if you can't get someone to take some of Ender's money - especially if Folty's not brought back.
