Lack gut runners in a team that is relatively slow and not highly skilled = get killed on the spread by the oppo and can't get space to deliver effectively into the fwd line.
If no Darling in the early games, poor OA is going to get battered b/n pillar and post unless we can find another tall to sit fwd in the pocket and at least take some pressure off him (he's a spud but but perhaps the only answer is Baily Williams).
Bet JK is not regretting retirement!
More worried about McGovern and Barrass to be honest. The amount of times they end up with their bodies being completely exposed against opposing outnumbers in aerial contests (due to no fault of their own) isn't sustainable.
The way the back line is (not)functioning, it's becoming only a matter of time before one of them ends up with a collision injury that causes them to miss a sizeable part of the season.
