In a vacuum, I don't hate this signing. As J.C. Bradbury points out, Wagner would likely yield more in revenue than it cost to sign him.
But it's the opportunity cost here that worries me, especially given the fact that the Braves rather curiously delcined to offer arbitration to Adam LaRoche. (What was the downside here? That he would accept the arbitration offer, and you would get the best first baseman on the market at relatively little expense?)
The Braves have a dire need at first base this offseason, they won't have much payroll coming off the books, and they've already blown $7 million on a 38-year-old reliever who is just getting back from Tommy John surgery.
We broke down the market for free agent first basemen back in October.
