Charles, this might have been fine in 2010. Maybe 2011-12. Hanigan can't hit second now. He will be a DP machine, he's very slow, hits 48% grounders, has 5 DPs this year in only 143 ABs hitting eighth (not behind a high OBP guy).
The Hanigan you are discussing, unfortunately, is not the Hanigan of today. The Hanigan of today has a .293 OBP, a .196 BA and no power.
