The fact that RT is dead last in long ball completion percentage says that every QB is better at the long ball than him right now. Let's not confuse the facts with statistical manipulation.
That's not what that says. That would only be true if all of the QBs were throwing passes under identical conditions. Obviously they are not. Different receivers. Different plays called. Different game conditions. Different defenses. Different offensive lines. etc, etc, etc
I wish people made fewer posts about "facts".
