Beane has some very tricky salary cap work to do next off season as they build for the future. There are a ton of guys that are due, some big, some immediate, some role players. I think their success as a team will largely have an effect on what happens for many of these guys. Not for Edmunds.
As much as this fan base (myself included) get frustrated by the style of play that @Shaw66 illudes to, Edmunds is their guy. Like Beane has said time and time again. They draft, develop and retain their own.
I have no clue about the money, and with big names like Poyer, Eddy O, Gabe Davis and Singletary needing need deals either this year or next, plus other part time guys like Phillips, Lawson, and Quessenbury, it becomes tricky to keep all the pieces.
Make no mistake about it though. He is a pillar of this team and defense, they will do everything they can to keep him here and maintain their defensive prowess with him roaming in the middle. It just means some of those priority role players walk.
