Talking about potential free agents for 2014 right now only accomplishes two things.
1. Illustrating exactly how bad this team is right now and that 2013 is another throw away season.
He is 37 and old knees. 2 years ago no one would have even said what you said. So after 1 solid year he has value?
I would call it he was healthy for a year and accepted his limitations and adjusted finally.
He is a risk and teams do not want to spend the quality type talent that Theo went and demanded in return.
They best spot for Sori is in LF with the Cubs. Bottom line.
