Do u agree the dragons need an 'X Factor' to go all the way and could it be NRL future star Kalifa Fai Fai Loa?

He is a future star, very similar to Akuila Uate, i think they might as well get some use before he goes to the cowboys, i reckon they need to drop Nightingale, not that he done all that much wrong, but i think Fai Fai Loa could be that X Factor that all the teams have, eg, Hayne, Barba, Carney, Campbell, Folau, Inglis etc, here are some of his stats remembering these are only from just 2 games, 2 tries, 4 Line Breaks, 21 Tackle Busts, and 20.5 runs PG, compared to Nightingale in 16 games who has had 10 tries, 11 LB, 44 TB, and 13.2 runs PG, the dragons really dont have any game breakers and they seem a touch flat and predictable (not saying that in a smart way, cos my team isn't going much/any better) but it seems they need some new blood and some unpredictability heading into the finals, just my thoughts, what do you think?
