The difference is the bat speed - Braun's hands seem so much quicker - I'm listening to the radio guys - and they were just talking about Kearn's "bat speed" - and how he's just not getting the speed he needs ... the swings do look similar though - Braun so far looks like the real deal - reminds me of stature of Nick Markakis ...
Also, Kearns body seems out of control during his swing, which may explain why he's lacking bat speed, while Braun moved his hands through the hitting zone and his head remained steady.
