When to go to the net, shadow defend, or go for boost.

Defending is more than just making saves. You need to know where to go, when to shadow defend, and when to go for boost. WhiffLess points out when you made the right decision, and there was a better option. It tracks saves, clears, and shadow defense time, so you know exactly what to work on. It also tracks exactly when you commit to a save, and whether you should have waited longer or perhaps committed earlier.
