The answer is yes. I was reading an article just before from last year about his level temperament and his attention to detail. I think they're attributes that suit his current role.
I think 2009 can only be looked at as a year for the coach to learn. I don't know firstly how much the Sonny Fai incident has affected the team. I would say he probably already noted the halfback crisis, given they practically went through every half with two legs whose played in the southern hemisphere in the last 10 years all of which turned him down. I'm not willing to write 2010 off, I don't think the adjustments have to be major, probably a slighlty differently structured off season working on stamina, ball skills and a bit of offensive structure.
I'd like to see him have an extra assistant on the defensive side of the ledger, I'm not sure what Campion's up to these days but he'd be the first bloke I'd ask, if not, Ruben Wiki holds a lot of mana with the boys and his defence even at the end was very strong. It'd free Ivan to look more at the offence. I would suggest he's come through a system at the Roosters that focused very much on the basics of completing sets and moving forward hard in defence, but I sense Ivan will evolve beyond that.
Ultimately, he has my full support, I wish he'd do away with the kick for penalty routine and I'd wish he'd make a couple more changes, but more often than not I guess he's stayed fairly true to a lot of players like Hohaia, Vatuvei, when they've gone through ruts and they've come out of it as stronger people.
