It wasn't just Cornes, Damo Barrett said it should be 10 and 30.To be fair, Cornes is a peanut and is quite transparent about his dislike for Richmond.
He shows very little understanding of the GCS/Rioli/academy situation.
I don't think 10 + 18 is far off. I think 10+11 is too much though.
That's why I'm suggesting something like 10 + 11 + 18 for Bolton + Baker + 24.
