This is an interesting one - Manly are changing their identity, and becoming the Giants.

It's a bold move, especially after they had so much success last season as the Wolves. To change their branding during the club's golden era is certainly a courageous move.
In the early 2000s, we saw several clubs form alliances with AFL clubs, many changing their colours and names. Most ended up changing back within a few years. Even here in Sydney, tradition is important to plenty of footy people.
And when zoning was re-introduced, there was nothing in it for the AFL clubs to keep the alliances going with no prospect of recruiting players from those clubs. Manly are zoned to the Swans, so GWS won't get any players from them even if they're called Giants.

Looking at the GWS Facebook page, it's caused a bit of angst among GWS fans. But any team can wear orange and call themselves Giants, they don't need GWS's permission to do it.
It's a nice photo op for the Manly club.
