Rampe is a very, very good player. Heath Shaw in his prime, Hibbo at his best id rate as valuable as anyone in our side, yes including Jobe and Hepp. Pearce Hanley at his best. Most of these players give away a bit in defense for attack though. and none of these players could play on a Rioli or Betts. The ones that I can think of that can are shutdown players (Nick Smith, Bagley) and do little damage running the other way. But still are very valuable. and no I would not pick a Nick Smith or Bagley at one.
I cant think of one player ATM that can lock down the likes of a Betts or Rioli, then be damaging the otherway. This is exactly what could make McG unique and as valuable as any pure mid.
I am not saying he will even be able to do this, he did show a lot of ability to suggest that one day he could though (in the under 18 champs).
One player who I think didn't get enough recognition last year was Aliir Aliir he has the makings to be a gun. He was missed badly in the GF.
