He played very well in the GF. I didn't watch so many Broncos games but in the ones I saw, that was one of his best. I know he also went pretty well in the game when JDB was marking him but Benji taught him a lesson in the first game against the Dragons last season.
I would agree as a fullback he is a superstar. As a 5/8 he isn't even close to that yet and I have doubts he ever will be. Remember he is playing behind over half the QLD SOO pack and 2 NZ internationals.
How can you claim he isnt any good as a 5/8 when you openly admit that you havent watched many games?
Milford started the season slowly, getting used to the workload as a 5/8 took time. By the end of the season he was back to being one of the most exciting players in the comp. If hes not considered a superstar, he will be very soon.
Also worth noting that he is a natural 5/8, not a fullback. The switch to 1 was a temporary move at Canberra to allow him to come into first grade and get used to the pace without being targetted in defense. His entire live he has been in the halves, including u20s QLD and Kangaroos teams.
