"A student should absorb everything, while also being self-critical and self-motivated to improve their understanding. Even as a young student, you can be your own teacher and critic. That is how you push yourself further." - Ryan Holiday, Ego is the Enemy
Holiday discusses the plus, minus, and neutral development structure. Ideally, we have a mentor from whom we learn, a student whom we teach, and an equal who challenges us at our level.
We have a cornucopia of resources at our fingertips with coaching videos (the FIBA series are outstanding), clinic notes widely available, blogs, newsletters (e.g. Mike Neighbors, Brooke Kohlheim), and coaching groups where coaches share ideas.
Video breakdown is similarly ubiquitous. For example:
Coach Nick at BBallBreakdown
Wes Kosel at HoopsChalkTalk
Zak Boisvert at PickandPop.net
Coach Daniel's YouTube channel
The greater issue sometimes becomes targeting your learning in a way that sequences our learning and incorporation (neuroplasticity), organization and teaching (transformation), and program assessment ("performance-focused, feedback-rich" environment). What did I learn from that? How can I share that? Did the players team and grow as a result? Can they function at a higher, pressure-laden level?
We can also study real-time what college and pro teams are 'running'. Last night the Celtics tested the basketball acumen of "3rd year rookie" Joel Embiid.
They elected to double across with Al Horford and Amir Johnson and rotate the x3 (Jae Crowder). Embiid is not an accomplished passer under pressure yet...on one occasion he got tied up and on another he identified ball reversal to the opposite wing but threw an errant (and late) pass leading to a shot clock violation. That's the education of a young player.
