THe buffalo and detroit families kinda just faded away as viable families because they had little union presence and thats all gone now and they missed out on the millions in the drug trade, whats left of these families is just gambling and some loansharking and extortion
The Buffalo and Detroit families are the next step down where New England, New Jersey, and Philadelphia are headed. I think, more than anything else, is that it came down to Buffalo and Detroit not having the numbers to withstand the general attrition. But, on the flip side, they obviously had more than, say, places like St. Louis or Los Angeles.
