We do not win the middle.
Start there.
Terrell May is an upgraded Alex Twal. Not a bad thing- he's a machine. But he doesn't win the contact. Sione Fainu is better at it. Samuela Fainu is better at it. Without trying to steal Payne Haas away, I would do away with trying to replicate Olokuatu in the backrow with Samuela & partner the brothers up front with May @ #13 & try & get metres through our middle.
The backrowers should be faster, danger runners. KPP coming in is one. Fifita is my pick as the other, if possible. Hassett, Garner...there are a couple of lower options...but Fifita has the ability to dominate.
Then you have Pole, Twal, Sukkar, Seyfarth, Hunt, Kit, Bird etc to play 3 of 4 bench spots (or other recruits).
Need a dummy half capable utility on the bench. Freddy Lussick is my guy, but there are others. Just not carrying a specialist dummy half who can only take the field at Api's expense. Gives greater versatility & allows for extra attacking flair.
Latu & Luai are the halves. Mason is a decent back-up development guy. We need someone we can bring in to fill a gap if Luai or Latu go down. Ilias would be great if he's willing to fight for a role- which is what he's relegated to at St George anyway.
We need to know what Taylan May is. He's a likely upgrade at either centre or wing- but is he a centre or winger?
Doueihi, who I love, forgets he has a winger in support, rendering Skelton to limited duties. To'a & Turuva are fine as a combination on the other side.
If May is a centre- I'd look at either Tyrell Sloan or Charlie Saab (Tartak client) outside him. Makes that side very dangerous through speed. (Tallyn swap for Saab..)
If May is a winger- I agree with some others, Gagai knows how to bring the winger into play & unlocks what Taylan May can bring to the team. As much as I want Doueihi at the Tigers- he does fail in this area. Gagai is an Aplha mentality too & we need much more of that.
Sweeping changes cannot & will not happen. So strategic tinkering is required. Greater depth & specific types of recruitment. It's not like the players are not trying. And it's not like all the players are hopeless. It's just not getting the best out of them yet.
