As an athlete we want to also explore larger ranges, this will prepare the body to deal with loads  when in unusual positions. Therefore, during performance when you are tackled or land awkwardly, your body will have enough strength and range to cope with these situations. Mobility training is a great way to mobilise your joints, it helps improve your joint range, increase nutrients to the muscles and maximises your movements. Mobility is 70% strength and 30% flexibility, in order to mobilise a joint one muscle must activate and the opposite muscle must relax—reciprocal inhibition.
