Something I am fond of doing with my coaching is asking players about their net statistics!
Bowlers: what % of your balls does the batter have to play? what % of a batter’s strokes would you say were run scoring balls? How many different variations did you try in a session?
Batters: how many strokes did you play that involved your ‘weaker’ side? How many different guards did you take (back in crease outside crease, leg, off)? How many times would you say you were out?
I do this to get the players thinking about how much they know about their game, how much thought are they putting into the net session, and week on week are they improving.
