Lowering the shoulder

Guard lowers the shoulder yet there is no displacement. We penalize the 6'7 guy for being an ox? That is essentially what I am getting out of this.....I'm gonna call it. The guard did a non-basketball movement in an ATTEMPT to gain an advantage. Tweet....PC foul

There's no rule against "attempting" to gain an advantage. Conversely, there's no rule allowing the advantage if the contact is accidental. "Intent" is irrelevant here.
If your 6'7" defender isn't moved, injured, or impeded, you don't have a foul. By rule, you shouldn't call this.
He's not being penalized for being an ox, because he wasn't disadvantaged. In fact, I'll bet the 5'10 guard will think twice about doing it again after he picks himself up off the floor a couple of times.
