It really seems like AA did his homework. Steamer has Navarro at 1.7 WAR and Kratz at 0.9 WAR for 2014. Not sure if they both combine for that type of impact, but overall, I really like what AA did here. It's the sum of these types of moves that could end up really paying off.
If the Rays made these two moves, many here would be giving more credit to the FO. With essentially no change in payroll, AA has improved this team and set himself up nicely to make a bigger splash having already addressed the most pressing need.
