After a wrestler takes an offensive shot, the defensive wrestler attempts to counter. Things like knee slides on inside step shots, and rotating to the corner on outside step shots are what I term "The second Exchange." In fact, as you get into a scramble situation in some cases, there can be a lot of exchanges before the take down occurs.
I feel that in order to develop a great offense from your feet, you have to gain the ability to transition from your shot into your second exchange, and based on reactions a third, four and fifth ect.
The transition from shot into finish needs to be continuous and fluid. The process will not work at a high level if it's a step one, step two, step three kind of technique. Chain wrestling through the exchanges after your shot is critical.
This second exchange concept is tricky to teach young wrestlers. I like to see kids drill the exchanges. I want the defensive wrestler to give a look and make the offensive driller transition through the exchanges.
In the normal progression of shot offense, you beat the head hands defense with your pre-shot set-up, how well the set-up works and how deep you get relies heavily on timing and coordination, this is the first exchange. One you have beaten the head hands defense, the second exchange happens. The second exchange is typically either fighting through the defensive wrestlers hips, or avoiding fighting the hips by making a corner. Once we have gotten this far, the third, fourth, fifth exchange, and beyond, is dealing with wizzers and funk.
I think wrestlers need to drill with a partner who can give them a realistic feel, meaning resistance at each level exchange.
