Mixed thoughts on those. I never care too much for the Captain's jersey, they're the kind of thing to flog off to collectors' although a NSW alternate to that one Qld had a few years back with all the pictures of iconic state attractions would be cool to see.
The 'smokey blue' adaption of the chevron jersey would look killer as a website background or an on-screen graphic during the telecast but I'll have to see the thing in the flesh and on TV before I make my mind up. The traditional NSWRL badge in the centre (on both) is overkill. Those jerseys would look notably less cluttered if it was absent and you only had the CCC logo in the middle.
Would LOVE to have seen this years' Perth navy blue alternate with that smokey blue chevron in the middle, could've even been tempted to buy if they'd executed it well. The Adelaide alternate must have been brought into concept by some hipster on the design team who looked back through NSW Origin jersey history and went "Hey, let's bring this one back ironically!"
If they were going to go retro, would've been cool to see either the early 80's striped sleeves one or the late 90's/ early 2000's one with the small white/ navy piping on the bottom of the sleeves. But if they wear that two-tone getup and run the steamroller through Qld again it might become an instant favourite...
