The good thing about the May pickup is that there is, genuinely, multiple ways that the rotation could be rolled out and, depending on opposition or general playing style, all could foreseeably work.
I'm probably going to change around a bit over the offseason, but I think, for now, I'm liking the look of-
*Bateman situation is obviously yet to play out..
May
Api
Klemmer
Samuela
Bateman
Bird
TDS
Hunt
Pole
Seyfarth
May to play 25/30 a stint, replaced by Hunt to maximise impact.
Klemmer, with May, have a combined efficiency of 97.1% and 105m/game. Klemmer to sub with Pole at 20min.
That'll take the sting out of the game and keep the middle pretty tight for the opening of games.
Bird to be used sparingly at lock as he is the primary backs utility and we'll need to manage his workload. Though I think people have underestimated his durability. Then have Seyfarth come on at 25 mins (ish) at lock to tighten up the middle around the likes of Pole who is notoriously poor laterally (hopefully on the improve).
TDS arrives at 25/30 mins for Api, just as we have our two wrecking balls in Hunt and Pole entering the game and the sting is out of the contest; handy for a young, undersized hooker.
In the second half, there remains a number of options, with Seyfarth able to play out the game, May can return early for a large second stint and TDS's minutes can build for a late Api flurry in the last 15/20mins.
In terms of cover, Bird gives us halves, centres and second row when starting at lock, Seyfarth ditto for edge and will actively and strategically reduce Bird's minutes if rotating primarily at lock.
But that's just one idea in a variety of approaches that can and would be effective in my opinion.
