So the K-Train video that Steve posted is a great add on if this fails first. I was working it all week in wrestling practice and a few of my wrestlers have actually picked it up better than me. One point that he didnt really emphasize is the pulling the elbow to the back pocket. If you put his arm in your back pocket at the same time as you punch over the neck I find it helps to counter the reroll.
Here is a vid Blackmonk posted that illustrates the transition from one to another
Also I forgot to mention that you can transition to a belly down position and a pirates crucifix for the tap or pin depending on your ruleset
