Liam Henry will float through half forward and the midfield (probably more forward early till he's built a bit of a tank). I see him in a similar role to Sonny atm, incredible delivery forward and decision making through traffic balanced with fantastic evasion and speed to get free. He's a great finisher with innate goal sense and will push forward to impact the scoreboard but you probably want him setting up the play from the middle before running forward to follow up.
Langdon's kicking and decision making has deteriorated rapidly over the past few years and for someone who is so often in space and facing little pressure, he has no excuse. I think he's an incredibly hard worker and knows where to go on the field to get the ball (probably my candidate for the Paul Haselby - good mark for his size award too) but when he turns it over so often and so poorly, I'm not too fussed if he goes.
If he does, I've said before I'd take Angus Brayshaw in a heartbeat and that hasn't changed. I'd also be happy with Melbourne's first pick and maybe an extra second/third rd pick or some combination of filler and pick swaps. We're gonna have a lot of empty spots on the list to draft in kids with all these retirements and trades so we need quality picks to replace them, not pick 80 and 90 in the draft. Good WA depth in the draft means it could be a good year to go hard at it for us.
