I honestly think (if we stay up) you will see Lui and Myler as our halfbacks, the main reason being I don't think there will be any relegation from SL next year to make way for a 14 team SL in 2021 (this should have been done for next year IMO)
Now, this won't be a popular opinion but I would be OK with that if we are not in danger of going down, lets go into next year with what we have got and be in a stronger position to be able to get who we want for the 2021 season rather than rushing one through for next year - maybe Mcllelland will have kicked on as well
