I would have assumed this was the route for Arnold, regardless of if Brands were to have come back or not.
Arnold has Senior MFS aspirations and the Olympic weight is 86 KG (~189.6lbs), which much better alligns itself to 184lbs than it does 174lbs.
I also thought for sure PK would be inserting himself in to this conversation - and he may very well still.
This now tells me that Mini-Focus is either going to... focus... on heading up to 197lbs, or keep it slim and stay near 174lbs for next season.
EDIT: Of note, PK, Brands, and Arnold all weighed in over 174lbs and under 184lbs for their Alpha Certification, whereas Focus weighed in over 184lbs and under 197lbs. It is a Redshirt year, so there might not be anything there. Interesting that his oldest brother's biggest competition is his training partner, though.
