BBS=boring but strong.
I am not experienced enough to say why you need OHP, but almost 100% of really strong and experienced dudes whom who I've learned about lifting say that OHP fucking rules. So I believe my elders in the subjects. Also, it is part of the program.
In the end you can do whatever you like. Only bench, only front squat, only clean instead of dl etc... You wont die and probably get bigger and stronger. But there is a lot of reasons why people endorse OHP.
Or take it as a challenge. Do you want to admit that you suck and give up. Things wont ever go smoothly with all the movements. Good example is the Alphaf. He was stuck with 500lbs bench for years until breaking the plateau one day. So sticking with OHP (and eventually beating it) will only make you stronger mentally and physically.
