"You can take certain aspects out of it as far as cleanouts and that sort of carry-on but the main thing it really helped with was having that individual sport behind you where there's no one else to rely on.
"It's just you. That's really given me the determination and drive in my training and where I want to go."
As a kid growing up in North Canterbury, Moody had more than his share of energy to burn.
"I was a bit of a naughty little kid and my parents took me along to get me to vent things out on the wrestling mat rather than taking things out at school."
With players such as Crockett, Corey Flynn, Ben Funnell, Codie Taylor, Nepo Laulala, Tim Perry and Owen Franks as options for the front row, the Crusaders will again have a major advantage in this area. As a specialist loosehead, Moody has Crockett as his main rival.
The Crusaders did away with their prop rotation policy once Ben Franks left for the Hurricanes, and it paid dividends in terms of performance and motivation for Crockett and Co. Moody, however, who played 16 matches last year in his first season with the Crusaders, will be expected to keep Crockett honest.
His fitness is a work in progress, Moody admitting that not being able to run wasn't doing him any favours.
"Generally my fitness has never been that flash. With not being able to do any running - I have only been able to do spin bike sessions to do my cardio - I'm a little bit worried where I'm going to be when I start doing things again."
Being able to get his hands on an All Black jersey after going so close last year was a burning motivation.
"I've been on a couple of training camps. That and being named [in the All Blacks], that's all motivation I can put in the bank to work harder and try to get back out on the pitch."
