Yeah, hopefully Devin comes in as a Spring enrollee and starts working at it. She made the USA U18 volleyball roster as a OH and will be competing in Mexico later this month, so if she starts, she'll be playing all the way around. She also plays all 6 rotations at the club level.
We lose Petersen and possibly Parra next season (Melanie liked a comment when someone asked her if this would be her last year at Texas on IG), but we gain Halter. So unless Heinrich is strong enough to play back row, Devin will need to play all the way around with Logan, since Halter will most likely be DSing for Skylar.
I honestly haven't seen any film on Kenna Miller so don't really know what her ball control skills are like...what I have read/heard is that she is hidden in serve receive at times, but she has a live arm and good hops for a 6' player.
I guess Jhenna could be an option as a DS player next season if they want to strictly go with SKT or Cabello at setter, but in a recent interview, she said she hated having that role her freshman year, prior to taking over setting duties from Shook...but she may not have a choice in the matter if she does decide to come back (she already graduated, but will be using her extra Covid year to finish her Master's program).
