how much does Jack Martin weigh? could he fill in there?
might see Tracey or Cam McG slotted into second row if we cop an injury
I was waiting for Burgess to answer but since you've already jumped in I will too
Now McIness is back on board we have good middle stocks currently, we can afford Talakai, Williams, Rudolf (my guess is that order) to do some edge work if necessary.
If you exhausted through them or needed them for middle then Reuben Rennie got a run in trials, or Colquhoun/Hazelton/Martin are middle options that are all probably ahead of Rennie, so maybe one of them comes into middle to free up the Talakai, Williams or Rudolf... or McInnes could probably do it also if you were that desperate.
Alternately you have the option of playing a back there if needed but it can be a big jump up in workload vs what they'd be used to and I don't think any of them are very attractive options.
Ikuvalu (184, 100kg), Jensen (190, 102kg), are certainly both big enough. Hiroti (187, 95kg) would probably go about as well as you could expect from your 6th choice centre/winger playing second row. I'd probably name Tolman at second row ahead of these guys tbh
I considered Martin also but don't know him well enough, as a prop he may not have the mobility to play there.
