Mainstream Deaf/Hard of Hearing & Coda Athletes is a list of athletes who are attending regular high schools (CODA means child of deaf adults). I played sports in high school and it was no big deal. I emailed the guy who is compiling the list to find out why he is doing it.
Sure, in volleyball and baseball, players often shout out, “Got it!” or “Mine!” — it was never a problem for me. Football is tricky because no one can move until the call is made, but I know there are deaf football players who have been able to work around that. Same for track or swimming, no moving till the call is announced. Just like everything in life, people adapt as needed to get the job done.
