Herschel Walker to Debate Opponent in Georgia Senate Race, But Why?

Based on the meme here, and what we already know, why on Earth did Walker agree to debate Warnock?

If you know you’re dramatically inferior to an opponent in a certain arena, why not stay a million miles away from it?

I’m reminded of trying out for the high school golf team, and my longer-hitting opponent suggested that we play from the back tees.  Ahhhh….no.

Herschel: Call in with a sore throat.
