True. Maybe you are built better for bench press as well. What does his back work look like? If you do all of those exercises you listed each week, you've probably got a decent balance between push/pull. Maybe he doesn't. If his back work sucks, then that's something to focus on.
Also, I've found that push press, push jerk, OH squats (that's for you Dan John), and OH dumbell pressing work with a full range of motion help me a lot with the bottom portion of the bench. Maybe try to get some low end work in with very pronounced ROM overhead pressing.
