Cutting practice reps is why rotations die in spring

Teams protect legs by removing the very repetitions that keep defensive movement automatic under fatigue.

Somewhere around February the practice court goes quiet. Full contact sessions get replaced by walkthroughs, shooting, and film. The reasoning is sound on its face. Bodies are tired, the schedule is compressed, and the games themselves supply plenty of load.

Then the playoffs arrive and the same team that defended beautifully in November is a half step late on every rotation, and everybody calls it fatigue. Some of it is fatigue. Some of it, I would argue, is skill decay in a movement pattern that was never as automatic as anyone assumed.

Defensive rotation is a decision problem executed at speed. Who do I leave, when do I go, how much do I give up on the pass behind me. Under pressure and tiredness the brain reverts to whatever it has practised most recently and most often. Take away the reps for ten weeks and the reversion target gets stale. Players do not forget how to sprint. They get slower at choosing.

The honest problem is that the two goals fight. Live defensive work at game intensity is exactly the braking load that beats up knees, so a staff cannot simply add sessions and call the debate settled. What they can do is separate the decision from the collision. Small sided drills at three quarter speed, with real reads and no bodies flying, keep the perception loop warm at a fraction of the tissue cost. Shell drill has been unfashionable for years. It should not be.

There is a cultural piece too. Veteran players negotiate their way out of these reps, and coaches let them, because the veteran is the one you need in May. The young players who do get the reps are the ones who will not play. So the team practises its worst defenders and rests its best ones, and then acts surprised in the second round.

I would also stop treating the schedule as the only variable. A back to back is expensive. A team that plays four games against opponents with three shooters on the floor is expensive in a different way, and the two do not add up neatly. Plan the practice week against what the games actually demanded, not against the calendar alone.

The cheapest defensive improvement available to most teams in March is twenty minutes of thinking on Tuesday.
