And late this afternoon, Fremantle confirmed that Marc Webb will join its staff in 2014 in a development coaching role.
Webb has most recently been the senior coach of Claremont in the WAFL winning the 2012 premiership and again taking his team to the minor premiership in 2013 before losing in the finals in straight-sets to West Perth and East Perth respectively.
The 34-year-old won 34 of his 44 games coached in his two years at Claremont following one year as an assistant at Subiaco.
Webb also coached Claremont to a Foxtel Cup title in 2012 and led Western Australia to a drought breaking state match win over Victoria in Northam earlier this season.
All up in two years as a senior coach, Webb has a WAFL premiership, two minor premierships, a Foxtel Cup trophy and a state match victory making him a prime candidate to now move into the AFL.
As a player in the WAFL with Subiaco, Webb played 175 matches and played in four premierships including captaining all three of the hat-trick of flags in 2006, 2007 and 2008.
That came after Webb began his WAFL career in 2001 with Perth after moving west from VFL club Port Melbourne.
All up, Webb played 195 matches in the WAFL, a handful more in the VFL and three for WA to go with the four premierships and losing grand finals of 2003 and 2009 before retiring at the end of the 2010 season.
In other movements, Rawlings has made the move west to reunite under his former captain Simpson.
Rawlings played 245 games for North Melbourne and won three best-and-fairest awards before retiring at the end of 2011.
The 32-year-old has been a senior recruiter and induction coach at North Melbourne for the past two years, and joins Simpson in West Coast's new-look coaching set-up following the resignation of John Worsfold.
Simpson, who played alongside Rawlings for 11 years at the Kangaroos, became Worsfold's successor earlier this month.
Rawlings, who was one of the game's best taggers during his career, said he was looking forward to reuniting with Simpson.
"I've always thought Adam was a senior coach in the making and I'm looking forward to working under someone I respect so highly," Rawlings said.
"West Coast's list has an exciting mix of experience and youth and I think we'll enjoy some great success together."
Simpson, who replaced John Worsfold as Eagles coach, still has several more appointments to make after losing assistants David Teague and Scott Burns.
Meanwhile, former Collingwood captain and premiership player Brown has joined North Melbourne.
He had spent the past three seasons working under Brett Ratten and Mick Malthouse at the Blues.
He joins Brad Scott's coaching staff at the Kangaroos less than a week after another highly-rated assistant, Leigh Tudor, joined the club from Sydney.
"I thoroughly enjoyed the last three years at Carlton and made some fantastic friends there and built some strong relationships with the players," Brown said in a statement.
"As disappointed as I am to be leaving, it's also a great opportunity for me to go across to North who are also on the way up.
"I'm really excited because I see North as being another club on the move.
"They have some fantastic talent there and are really exciting to watch."
Malthouse paid tribute to his departing deputy.
"In his three years at Carlton, Gavin has developed a great relationship with the playing group and displayed a level of excellence across all facets of his coaching," Malthouse said.
Premiers Hawthorn have also made several changes to its football department with Cameron Bruce moving to being an assistant after spending 2013 as a development coach.
Damian Carroll has stepped down after guiding the Box Hill Hawks to the VFL premiership to become the head coach of Hawthorn’s development academy with Marco Bello taking over the VFL side and also working as a development coach with the Hawks.
Former Melbourne star Adem Yze has been working with the Hawks on a part-time basis but has now also taken up a full-time development and specialist coaching role.
