People argue all day and night about Avon & Stringer and miss the most obvious point. Avon and Stringer were the same coin, different sides. Yin & Yang. Muscle & Smarts. Without Avon's muscle, Stringer would have the crew looking weak out there and he needed someone to keep him grounded, otherwise he would kept getting played by them downtown boys thinking he was really Gordon Gekko instead of a drug dealer. Without Stringer's wisdom, Avon would be out there going to war with a bunch of young nikkas over some dumb ass corners. He'd never see the big picture. Also Avon needed someone to make hard decisions. String wasn't tougher than Avon but, he was smart enough to know D'Angelo and Wallace had to go. They were a perfect team.
They were way better leaders than Marlo. It was more a family thing over there. I mean, you can only trust drug dealers so far
but, Avon had basketball games, dinners, after parties at Orlando's. N*ggas took Stinkum out to eat when he got his package. With Marlo, it was none of that
one mistake over there and you were covered in lime
Marlo was so dumb, he bought all that attention on his organization with all those bodies and was out the game quick while Avon/String went unnoticed for almost a decade.
