what are three reasons why Jeffrey gets the nickname maniac?

From the text:

The kid who intercepted Brian Denehy’s pass to Hands Down and punted it back longer than Denehy himself ever threw it.

The kid who rescued Arnold Jones from Finsterwald’s backyard.

The kid who […] circled the sacks on a bunted frog.

Nobody knows who said it first, but somebody must have: “Kid’s gotta be a maniac.”
