Your main issue is that you are putting on the rub right before you put the meat on the pit, and the picture shows that clearly.
If I'm gonna rub the meat right before cooking, I'm gonna let the meat sit out a little so the rub will start soaking in easier. Some folks start with a light sprinkling of salt (kosher, pref.) on first, and this draws moisture to the surface to absorb the rub. You want the meat to have a wet look to it before putting on the cooker, not like you just poured the seasoning on. This takes a little time, especially if you're not gonna let the meat lose it's chill before putting on the pit. (Rub the meat hours in advance if you're concerned about the smoke ring.)
