Research can help us understand how athletes learn. Coaching connects that understanding to a player, an assignment, and the next rep.
Sideline Science brings those conversations together. The newsletter explores the evidence. The Equipment Room gives coaches resources to organize their teaching. Friday Night Transfer is the coaching principle underneath it: prepare players for the decisions the game asks them to make.
