I've been against trading Lycett, but if you have a look at teams that have won flags over recent years a strong midfield is much more important.
Why couldn't NicNat be our main ruck and Kennedy play the Roughhead role? Having 2 gun ruckman has been nice, but most of the time it just means that the opposition roves to them anyway. Geelong haven't got any rucks of note but are close to flag favourites. Hawks have Hale... enough said.
If NN goes down, although we'd be limited in our replacements, Sinclair will do, or could get a second / third tier ruck from another club through free agency or something.
Getting another pick in the top 10 this year might not be a bad idea even if it does leave us thin in the ruck stocks.
1) Hawthorn have made it pretty clear they want Bailey and Hale as the ruckman leaving Roughhead and Franklin as tall fwd targets. (Hodge admitted as much OTC last night).
2) Having another top 10 pick in no way guarantees you getting the pick right - esp WC.
3) Lycett is a far better prospect than Sinclair and to place hope in "getting a 2nd/3rd tier ruckman from elsewhere" is foolish.
No doubt having another top 10 pick would be nice - just not at the expense of an up and coming ruckman. #1 however is a different story.
