I think a lot people are underestimating just how good Sam Jacobs is for a 23 year old.
Remember, Carlton had Kreuzer (gun), Warnock (bean stork who they traded heavy for with the potential to do anything if he has heart) and Shaun Hampson who was a Priority Pick the same age. Carlton's young ruck stocks were amazing and they just could not afford to pay Sam Jacobs who was out of contract what Adelaide offered. Looking back we should have been all over him because he walked for approx. $350K a year as a 22 year old and will now lead Adelaides ruck division for the next 8 years.
Adelaide promised him first crack at the Number 1 ruck spot and from there he has been excellent and shows that that trade Adelaide made was spot on. I don't understand people saying because "Ivan didn't play much this year" it is a huge negative. Well, Sam Jacobs only played half the games the year before because Kreuzer and Warnock war taking all the time and that was before the sub rule.
I have no idea if Ivan is going to be any good but the benefits for this team if he is will be substantial because we have some absolutely ripping young players.
