Well if we are rebuilding then why not internal options? If you must sign somebody then find someone for a two year deal. There should be several 1-2 WAR players that could had for that. Going long term for an average player just to fill a spot when you are rebuilding doesn't make a lot of sense.
You can rebuild and still use the money allotted for your payroll. The Braves were going to have a 110ish million payroll anyways. We should just sit on that extra 25-30 million and let Liberty pocket it?
