Cook you're being oversimplistic, doesn't matter how big the area is. Someone could be running a 100 million dollar betting ring on a small street corner in Gary, it doesn't take an entire crew to oversee that.
you do realize that soldiers and some associates have crews in Chicago
that Anthony calabrese guy being an example
a few guys wouldn't be able to keep watch over that much territory
they might not be their own bosses but it's still a crew of guys
