No rotating hips equals shank

[HerdGolf]

I've worked hard over the last several months getting the swing where I want.  Guy I take lessons from says I'm just a hair under the plane on the backswing, but nothing he would change.  I have a good lateral shift of the hips forward to start the downswing with the arms lagging behind as they should.  The problem is if I don't make the hips to rotate hard I shank the irons and hit close to the hozzle on the driver.  Anyone have an idea why this might be happening?  I can see in video that my hips freeze after the lateral shift until after I hit the ball unless I really force them to spin. It doesn't concern me expect when I'm trying to take something of  a wedge or lower iron.  I tend not fire the hips fast which on the range equals shank.

My though on shorter irons and wedges is to make sure my back elbow is tight to my hip or side.  You can't swing and stop or slow the hips.
