^^ agreed. Its like saying all you need to do is standard curls for biceps. Yes its a group of two muscles, but there are many different things to develop in it. Length, width, peak, ect. These muscles that are designed by nature to assist in push/pull in many different directions also need to be trained this way for full development.

Kinda silly that this is even a debate. Its accepted by preatty much ever bodybuilder whos even somewhat serious about their training.
