He's been outplayed by Bont, Higgins, Parker, Pick any name from the Gold Coast game, and broke even with an injured Cotchin. This defensive mid stuff is interesting given the midfiled performs best when Guthrie isn't in there and he hasn't shut any dangerous opposition mid down all season. I don't see it as "who's a better player" because we know what we get with Guthrie, he isn't getting any better so I'd like more opportunity for the young guys as their ceiling is much higher and any fast tracking we can do now will only help in the future.He is playing as our most defensive midfielder, which given his backline experience, makes sense. His tackle numbers are elite and he often plays on the oppositions most dangerous mid at clearances - in particular, centre square bounces.
There is always an interesting idea, "who is a better player" and then balancing that with the mix of players you need to win a game. The argument here is that there aren't too many other options to play his role. Scooter would be an obvious choice, let's be honest though, he needs to show that his body can handle the game.
To be honest I don't really think the club should be looking to play younger players in the AFL unless their form, structure and management all align. They can develop in the VFL just fine. This year is about going 22-1 and then on to a flag.
(Constable could never play again for all I care as long as we win the flag this year!)
Going off your criteria for playing young guys we wouldn't have had any debutants round one. These guys are a driving force behind our ladder position right now.
