I say he's in the bottom half of all SS. He looks better than he is because he makes flashy plays that basically are caused by him being out of position and having bad range. The spectacular "in the hole" plays that he makes are plays that most other SS make look routine. I say he's easily the most overrated defensive player in baseball. The fact that he has one Gold Glove let alone several is a joke.
He does have great leadership abilities and the calmest eyes I've ever seen though.
