Take 2 more weeks and it's basically 200k.
Make it 75 a game and it's 210k.
Throw in a single 100 in round 3/4/5 and it's 200k if he scores ~65 the other weeks.
For mine from Daniher down there are probably a total of about half a dozen other rookies that I'd put any kind of money on to average 75 while there are 3 in the rucks.
FWIW Daniher, Impey, Dow, Campbell, Cahill, Phillips, Downie and Scott probably the only ones right now and I'd say most of them are less likely than likely.
Your key distinction is you think his role is going to be significantly better in the real season than it was in both preseason games. He played as a forward pocket, a genuine forward pocket, in both games. If he plays as a genuine high half forward he's a different prospect but I can't see him beating Greene, Green, Taranto, De Boer and Coniglio out of those spots. Greene is an AA, De Boer was very good in the role on the weekend and the first choice midfielders will rotate through there well ahead of an underdeveloped kid who has missed the best part of 2 seasons.
I really like him but his role is probably the worst possible role for fantasy purposes and he's got next to no forward craft, those guys you want to compare him with are genuine forwards in the role and still struggle to score from it. It's very hard to score in that role because you're confined in the ability to spread and roam, not a target on most forward entries and essentially have to create goals. Generally it takes elite pressure skills, which he hasn't shown, to push to a higher tier 65+ scoring in that role.
Basically assuming that one of Scott or Downie is picked for round one you're picking Bruhn at M11, for mine 160k is a lot to pay for the deepest bench spot. It's something I do if there are no rookies but outside that I just can't see the cash generation. For mine Pickett remains the best comparison for him last year barring 3 or so midfield injuries opening up a role for him in which case you can just downgrade into him as I suspect he's still going to be around 175k in a month.
Been wrong plenty of times but it's very rare that a rookie plays a role like that in the preseason and then moves up in role as the senior players missing come back in, especially when he goes and does the worst thing possible by kicking a few goals from it!
Also there is a reason that teams keep drafting mature aged genuine forwards to play these roles, it's a specialist role that is actually very difficult and being a good midfielder very rarely translates to being good at it, the skillsets are actually quite different.
FWIW I really liked what Henry showed, playing out of position against the best side in the league. He was considerably better the week before as well.
He'll be a good 3rd tall, decent below his knees and should present a lot. Long term he's a Tom Lynch type (Adelaide) and think he'll be a very useful player. Should work well off of Mihocek and will definitely prefer the 3rd defender over getting the top defenders like he did in preseason.
Still, young guy in a team that is a bit unknown after their exodus, with a couple of other targets is not a good fantasy role to me but I do think his JS is pretty solid and that he's capable of some alright scores. As I've said before though, I wouldn't be paying extra over Harrison Jones, they're as similar a pair of fantasy picks as you could find but with Rowe already a better bench option I think there's hopefully only a need/place for one and 12k is 12k
