Just figured what Aaron Hicks is doing rong at the plate. In the movie "Blazing Saddles" there's a dance scene where gay dancers push their hands forward while pushing their asses backwards, singing, "...that's why they're doing the French Mistake..."
Yup, Hicks is doing the French Mistake. It's not as obvious as in the comedy, but the effect of letting your rear hip trail behind the swing accomplishes the same thing: no power, no reach, lots of weak pop-ups. The rear hip has to torque in front of the swing, dragging your hands along for the ride. Right now Hicks is faking it, trying to make it look like he's turning his hip, but it's actually trailing. The result is a weak arm swing, not a body swing.
The only real way to cure the French Mistake is to whip the bat thru the zone as hard as you can, over and over, then do that when you're at the plate. Turn the hip, then let it rip.
