Edge defense is probably the biggest thing for me, quite a few missed tackles down both sides.
Also need to improve our left hand attack, the first try came from a Taupau offload and the second was from some Johnson magic so I'd like to see something more there. They went to Liu a lot with the short ball but never really managed to create the gap for him to get through so might need to put that one on the shelf for the time being. There were quite a few chances where we sucked in the defense and had Maumalo unmarked on the wing so hopefully they keep that in mind next time and look for the long ball.
I'd like to see the team use Dallin Watene-Zelezniak more in the attacking 20, there were a few times where they had a setup where he'd run the inside line or the sweep role but the ball just didn't seem to find him much.
Missed opportunities also got us, Johnson and Smith both missed out on what should have been tries. Johnson should have pinned his ears back and Smith needed to play closer attention to what he was doing. Kata would have been wrung out for 3-4 pages if he had grounded the ball on someone's foot while looking right at it. Think those two will definitely be regretting those.
The mid to long kicking game also needs a bit of work as well imo.
