The Gemara's askafta of today's daf (81) asks why can't the pesukim be describing many chiyuvei sekila, starting with ben sorer umoreh.
How could a ben sorer umoreh be chayav sekila, and still become a gadol in time to be over the other issurim?
Gershon
A Ben Sorer is already a Gadol (Sanhedrin 68b).
