Well, it's a complicated answer unfortunately (
)
Acres has one wing spot wrapped up for sure.
The other was expected to go to LOB (O'Brien - and still might, a Hollands debut does not mean it's his wing, as you need 3 wingers in rotation for any given game etc)
Hollands was probably 4th in the pecking order (behind Cottrell, who is currently injured, expected back in the early rounds) however it's quite possible they play 3 of Acres/LOB/Cottrell/Hollands in the same team going forward.
I would feel a lot better about his scoring potential if LOB wasn't named for Thursday night's game, then it would be safe to assume Hollands would play pure wing (80%, whatever his TOG is etc) and is currently ahead of LOB. If LOB is named, Hollands is much more likely to play forward of the two, and fill in for Acres/LOB on the wing when they are on the bench.
Throw in Walsh as another that would have a minor affect on Hollands (with Walsh in the side, one of Walsh/Cerra can fill in the wing time of Acres/LOB etc, so you don't need to play "3" wingers)
