FSP's, the best way to gain ligament and tendon strength?

Coach,

As the title succinctly states, my main question is are FSP's the best way to gain tendon and ligament strength? If not what are some ways to increase this element?

Its an important foundational step. Once enough strength is there, then plyometric movements are the next step.

Thanks! Do you or does anyone else have further ideas? Particularly wrist preparation?
