Fister deal means money saved in comparison to a decent 1 year pitcher (see deals for Haren, Jackson). ZNN and Desmond arbitration deals also free up money.
Balfour is good. It's good to have good players.
Balfour is old. He'll sign a short term deal. 1 or 2 years. (already agreed on 2 for O's before that fell apart).
If 2 year deal, will be here when Soriano is likely booted to the curb helping to ensure strong pen for 2015.
Another strong bullpen arm could lead to a deal. Who gets dealt? Clippard : expensive (for the Nats), good, closer to FA (more appealing for Nats to trade). Storen : cheaper, good (certainly historically), more years of team control (more appealing for team traded to). Soriano : THEY WISH!
