Michael has a very clear idea of what his problems are, but not a clear idea of how to fix them. From the video you will see that he has an excellent swing, and that his most glaring issue is just what he thought it was, the use of his lower body in the downswing. I compare him with Rory and the difference there along with the explanation will (I hope) help him retain his hip depth and to clear his left leg much better, which in turn will allow him to get his hands more forward at impact and to sustain his bent right wrist/flat left wrist past impact.
