debatable

not debatable

too obvious

Explanation:

The statement about professional athletes getting injured on the job despite safety attempts is a claim that can be debated. It's not "too obvious" as the extent of injuries and safety measures' effectiveness can be discussed, and it's not "not defensible" because there's data (like injury statistics in sports) to support or refute it. So it's debatable.

Answer:

Debatable
