Angelo Prisco was recorded on tape saying once you're in the can, it doesn't matter, unless youre boss.

Ducks was in the can, no title.
There's no power there.

It was also understood that when a boss went away for life, his duty was to pass the crown.

A (one of many, but not negligible or irrelevant )cause of the Persico/Orena conflict.

Power is fickle at thr best of times. Especially in the quick changing areana of the mob.

Stability and longevity are a rarity, not the norm, in that world.
