Granted Crossland even said he was actually letting Cogger set things up and he was just playing a running eyes up role.
So Crossland wasn’t actually doing anything it was Cogger setting up the play and Crossland was just going with it and playing eyes up.
(If you’d want to look for the article you prob could but I don’t want to)
This to me fairly straightforwardly answers the question of "can Dylan Brown play halfback in the NRL?" What is a halfback and what is a five-eighth, really? Alfie Langer, Ricky Stuart, Cooper Cronk, Ben Hornby - all halfbacks. Anthony Milford, Ezra Mam, Blake Green, Kieran Foran, James Maloney - all five-eighths. Johnathan Thurston, Jarome Luai, Jake Clifford, Luke Keary and Luke Brooks are all going to play a lot of footy with both 6 and 7 on their back.
In some teams, 6 & 7 just indicate left and right. Munster and Hughes are very very similar players, robust run first halves who have strong kicking games and play a very ad-lib style. I don't think there's actually much difference in their roles at all, besides where they stand on the field.
But the closest thing to a consistent definition is the 7 is the "primary" half and the 6 is the "secondary" one. Someone like Mam plays the secondary role by playing almost a purely eyes up, run-first, support play-heavy style, while Reynolds does most of the thinking. Blake Green did it by doing the opposite, not even touching the ball that much but focusing heavily on constantly talking and making sure everyone is setting up correctly for what the team is about to do next, and playing an unselfish style focusing mostly on just getting more dangerous players into good positions. Then you have someone like Maloney who sort of wore both those hats at the same time.
Probably not a coincidence: Mitchell Pearce looked like a much better player next to someone like Blake Green or James Maloney than he did with Connor Watson or Kurt Mann as his 6.
Could you drop Brown into just any team, and have him play halfback? No.
Could you drop him into the Knights next season, put the 7 on his back as a way of telling him "you are one of the main men on this team, we are going to look to you to create points for us the way we look to KP", and post Cogger & Gamble on that right edge as a Blake Green style "supporting half". In my opinion, yes, absolutely.
I don't think the issue with the spine is a lack of players who can competently steer the team to the right spots on the field & then get the ball where it needs to go. The issue is a lack of quality & threat besides KP.
I honestly think that solves the halves question in the short term, and then whether guys like Sharpe/Pryce/Votano/Loza force their way into the team, whether Brown's role changes to more of a key organiser one to accommodate that, that's a problem for the future which can be solved at the club's leisure, rather than trying to force it ASAP.
