Do they have a Hudl account set up by the coach or the team?
If so, they can do it within Hudl and then share the link with Hudl highlight video.
Now if the video is your own... I like Movavi as a video editing software.
Making the video is just you taking the time and putting the clips together... the next question is if it isn't Hudl... you will need a hosting site..... maybe create a Youtube account and put it there.
