Yes, Bonifacio's OBP is .028 better but that's outweighed by Presley's .060 slugging advantage going into this season. Presley had some better tools, Bonifacio had some better tools. At the end of the day, both are a half-click over replacement level players (and neither are that different from Sam Fuld, either). After a hot start, Bonifacio has OPSed at .580 over the past 28 days in 95 plate appearances. He's simply not a very good player and until Presley's weird implosion, they were basically the same guy give or take a little here and there. Going into 2014, Presley was a 1.5 WAR guy in ~820 PAs, Bonifacio was a 4.0 WAR guy in ~2300 PAs.
