There were a few that he was a top 10 offensive AND defensive player. Usually a guy is one or the other, not both. He was able to play great defense at multiple positions. Rafaela plays great defense at just CF (average defense at 2b if that) and his bat lags way behind a guy like Zobrist. If we believe Rafaela is a 2 WAR guy, Zobrist is twice as valuable as Rafaela in a regular season. In a great year, he's multiples of that.
