Allow steak to sit out at room temperature for one hour.
Light one burner (far left or far right burner) on your gas grill, and place an optional smoker tube over the active burner. Close the lid and allow the grill to preheat to 225°F.
Season your steak liberally with steak rub, and insert a leave-in meat thermometer.
Place the steak on the grill over indirect heat, close the lid and allow the steak to reach an internal temperature of 110°F. Remove the steak from the grill.
Turn all burners on the grill to high or max and close the lid. Allow the grill to get as hot as possible for ten minutes, heat soaking the grill grates.
Place the steak on the grill grate over direct heat. Flip the steak every 30-60 seconds, positioning it in a new spot on the grate every time. Continue flipping and repositioning the steak for 5-7 minutes, or until you have achieved the desired crust.
