Timing Up & Unders by Cat Phillips
Defenders can often read what a cutter wants to do in advance to re-position themselves to deny an option. When cutting, it is therefore good to be able to make split-second decisions about where you want to cut.
A thrower, A, stands near the middle of the field and is marked by D1. Two cutters, B and C, start 10-15m downfield.
D1 > A > B > C
Cat Phillips says:The second cutter, C, needs to make a fast decision about whether to cut in or out.
Learn to check in with the thrower during cuts (i.e. get eye contact) in order to better time your movements.
