Yoga for Sports

Hi Everyone! Hope you are all doing well.
I need your opinion, advice, information etc. on a topic. I will be teaching the sr. volleyball team yoga in the fall as part of their sports training. One thing the coach wants is 'visualization'. I don't really know what to do with that. Does anyone have any ideas about what I can do. I will do some meditation practices with them, but that wouldn't be sports specific. Do you think this is good for visualization in general? Should I do sport speciic visualization techniques?
Thanks for the input.
