Career is about to blow up
With Paul Walker's death, the F&F franchise (which only seems to grow in commercial profitability) will need a rugged white dude with a heart of gold to fill that void. Since Lucas is already a part of the franchise, he's definitely about to see his star rise with the 8th and 9th films.
Comic relief - Tyrese, Ludacris
Muscleheads - Rock, Vin Diesel

White dude - Lucas
Might sound cruel, but everyone's bad luck is almost always someone else's good luck. It's how the universe maintains order and balance.
