In a ceremonial changing of the guard, the 20-year-old will now wear the number of the man with whom he shared the Western Bulldogs' forward line intermittently over his first two seasons in the AFL.

"He was keen to have 13, and I was keen for him to have it," Giansiracusa said.

Their time spent together was intermittent because both players were in and out of the team, Hrovat took turns rotating through the midfield, and Giansiracusa spent 17 games over his final two years as a player trotting the boundary line as the team's starting substitute. Thankfully for Hrovat, he is unlikely to receive a Giansiracusa gift pack, complete with green vest.

Over two years, Hrovat has received plenty of counsel from the veteran Giansiracusa and can continue to do so now with the old silver fox who has replaced the fluoro vest with a polo shirt  and a spot assisting Luke Beveridge in the new-look Bulldogs coaches box.

"Obviously I've looked up to Gia over the last couple of years, he's really helped me coming into the club and playing as a forward, so to be able to take his number is a real honour and with him still working at the club it's real fun, and there's a lot of banter," Hrovat said on Monday.

Hrovat's 7 senior games in 2013 became 12 in 2014. With his stints through the midfield becoming more pronounced as the year went on, he is ready to capitalise on the departures of veteran onball duo Ryan Griffen and Adam Cooney.

"Definitely, I think there's a whole group of us that can sort of put our hands up now," Hrovat said.

As forwards coach, Giansiracusa hopes that he can hang onto the youngster as much as possible, knowing the value of both his contested ball-winning ability and poise around goals.

"He's got such great attributes. I hope he stays in the forward line. But he's definitely got attributes to play multiple positions. He's a pretty special talent and one we're really excited about," said the coach.

Helping Hrovat's cause is that he is fit and firing. He is yet to complete a full pre-season, with a string of minor complaints - a calf here, a quad there, a fractured cheekbone in the 2014 NAB Challenge - all slowing his progress. As such he has played only one game prior to June in either 2013 or 2014. Things seem different this time around.

"I've been fairly injured, so at the moment it's just about getting through each session and managing my body well," Hrovat said.

"It's actually very exciting. I'm getting to know my body a lot better. I can tell when to pull back and when to go hard. It's all learning, and I guess over the last few years being injured it's sort of made me realise when I can push."

Tuesday marks 100 days since the Bulldogs lost to the GWS Giants in Giansiracusa's 265th and final appearance in the AFL. It would be hard to comprehend that a club could have had a more tumultuous 100 days. Captain, coach and Brownlow Medallist out, No. 1 draft pick key forward, logo and new coach in.

Much has changed, but Giansiracusa says the transition over the fence has been a smooth one.

"It hasn't been tough. I've really enjoyed it. It's different, there are a lot more hours than when I was playing."

He feels as though he's striking the balance well in his new relationship with his former teammates, knowing when to have fun and when to take a more a serious approach.

Having only ever met new Dogs coach Luke Beveridge on a family holiday in Bali, Giansiracusa didn't know what to expect. Rest assured though, things are going well with the new alliance.

"He's a really humble guy and really easy to talk to."
