I think every coach has had the situation happen before where we use a lot of coachspeak and the players look at you with that puzzled look. And then you use a different word and then it instantly clicks.
For years, in teaching M2M defense, I've always used the term "hedge and recover". To me, it seems natural, I've been around coaching long enough and I always thought it was a universal term. But I can remember the many times that I've tried to teach it to players and some of them got it, but from others I would get the puzzled look. They problem is that they really don't understand what that means, what does it really mean to "hedge"??
I was watching an old school Mike Krzyzewski DVD on M2M defense (I converted it from VHS and isn't available anymore, but this Coach K DVD on Defense is basically an updated one) and in it he talks all the time about the "fake trap". After hearing that, I instantly thought to myself, that is what I need to use to better communicate it to my players. I'm watching the players move, and Coach K is there saying "fake trap" and they're really getting into it. The motion is exactly like going to set a trap, but backing out -- a fake trap.
There's all kinds of coaching jargon that gets in the way of getting your message across to players. Although we take for granted, the many terms we use, we have to assume the players don't know what the heck we're talking about the majority of the time, and we also have to assume that not all terminology is the same from team to team, school to school -- ie. there is no universal terminology. I'd be interested to hear if you all have others out there that might help all of us out.
