Pop up nets.

Today I am going to put my money where my mouth is. But I need your help too. This is a cricket skills case study about me: I'm going to report back to you on a goal so you can see how these methods work and take the ideas into your game. I'd love you to come along for the journey too.

Last week I wrote about how constraints led practice fast tracks development of batters against spin.

Last night I was faced with my own set of constraints as my beloved Millfield cricket "bubble" indoor facility was flattened by 'Storm Clodagh'.
