Without Taysom's athletic ability Christian has to live or die by his arm alone. He has done well to work on it and I think he is a better passer than Taysom. Or perhaps Anae has put him in better positions via play calling rather than lazily sit on the sideline waiting for Taysom to rip off a 50 yard run with his legs.
Either way if you could give Taysom Christian's accuracy that would be awesome.
