what's the edge watson will never forget why

I’m not able to pin down what “the edge watson” refers to from that wording alone. The most likely reading is that you mean a person named Watson and a specific “edge” or memorable moment, but the search results are too mixed to identify it confidently.

What I can tell

• “Watson” appears in very different contexts, including sports and unrelated articles, so the phrase is ambiguous.

• One result ties Watson to “edge” in a sports context, but it does not match your exact wording or prove the intended meaning.

Best next step

Rewrite it with one more clue, such as:

• the full name,
• whether it’s a football player, actor, or forum user,
• or the exact quote/post you saw.

Right now, the safest answer is: I can’t determine why Watson “will never forget” from this phrase alone.
