I think your coach was great and respectable !!
In my case, when I was a highschool student, I belong the tennis club and my coach was very good like Hiroki's coach. Although he was fifty years old, he played tennis very well and he sometimes defeated us highschool students in tennis match !!!! It was amazing ! From his lesson, I learned a lot of things. He still plays tennis actively now. He is the person whom I respect.
