Straight Front Leg

Is he loading his hands against his stride?

If you keep your front foot closed you may be less likely to "bleed" power through a collapsing front side. Also, just keep working on staying back, let the ball travel to you.

thank you for the replies... he starts with a fairly balanced stance, 60 / 40 weight on back leg. He loads his weight and hands back and separates from the front leg with a small stride. Weight transfer seems to be fine. He just has a tendancy to drift forward on some swings resulting in a slighlty collapsed front side. Mostly due to when he does not get good hip rotation. He does alot of cage work, including T-drills, short toss etc... any recommendations on best drills to help make this part of his swing more consistent?

I appreciate everyone's input.
