hmmmm . . . I think people are making Layer 17 way too complicated. Here are a couple of quotes from Rick and the R&R Disk set. 1) Transition is . . . "How to get from Defense and Flow into Read & React Seamlessly." 2) Rick says, "There is no concrete rules about Transition (Primary and Secondary). It is simply a WAY to get INTO the Read & React". 3) and a final quote (when he talks about Triggers), "A 'Trigger' is simply an action that occurs to begin a new action. For instance, Failure to get the ball into the Post is the 'Trigger' that ends a 'Primary Break' and starts a 'Secondary Break". Failure to execute the final action in the 'Secondary Break' triggers the beginning of the 'Read & React'. Reading the Player with the Ball (Pass & Cut, Dribble-At, Reverse Dribble, Power Dribble, etc.) 'Triggers' the beginning of the 'Read & React'." So, I interpret that to mean that ANY transition IS Layer 17: Transition Offense (no matter how simple or sophisticated). In the Read & React disk set, Rick uses an "example" of a "Random Transition into Read & React" that has everyone basket cut and fill-out to Spots. This may look different every trip down the court. In my most recent post above, the third line states . . . "You can transition dozens of ways, but the fact is you must transition!" Whether it is a "simple transition" or a more "sophisticated" transition, it is in fact Layer 17: Transition Offense. My contention is, why not teach that "Transition" phase after each Layer you introduce. That way, you've got your half-court R&R teaching, then discover your best 'Trigger' from your Transition into R&R by teaching Transition Offense ASAP. More importantly, kids love to play Full-Court. Why not break-up the monotony of Half-Court "teaching" with Full-Court "Fun"! Just thoughts . . .
