There may be less scope for growth but at the same time they are more mature both mentally and physically. Imo Ruggles is a good chance of promotion, more so than others although not guaranteed.
If you look at it this way, at 23 why would we rookie him to just sit in the vfl when he was already in our vfl side? If that was the intention we'd have taken a punt on another 18yo in the RD. That says to me Ruggles could very well be one of the promoted rookies.
It's no different from us rooking Sherringham and Simpkin, after strong VFL form. Both were treated as depth and didn't get much opportunity.
There are many benefits to rooking players from our VFL list. It would help us recruit more talented players onto our VFL list. It would also encourage those players to stick around longer.
