Not for nothing but scarfo was a boxer i believe gotti wasnt and merlino was a jockey. So scarfo probaly had better hands then most mob guys even if he was the size of connor McGregor
McGregor is 5 ft. 9.
I've seen Scarfo listed everywhere from 5 ft. 2 to 5 ft. 6 but I'm inclined to believe he's around 5 ft. 4 cos he wore lifts.
So, no, Scarfo and McGregor are nowhere near the same height.
McGregor is the same height as Gotti and just one or two inches shorter than Gigante, Massino & Castellano - who are all considered tall.
