Yarran vs Lecras vs JJK

[the captain]

I can go for 1 of the 3, just not sure which to go for. Disadvantage of Yarran is that I will have to play a fwd rookie, but if I go for the other 2 there will be 3 starting rookies in my backline, which there are more than enough options for.

Ps. I know Lecras/JJK has been done to death, but felt I had to add both of them in.
