As a former volleyball player i'd put her at least over Cara and Iris, who aren't into any physical activities(other than sex
).
Nikki is probably the strongest.
Sha'carri(if she counts) and Val after Nikki(they are elite vs the other track girls).
Gabi used to be an athlete too, probably lost some strength since.
Elena next, those jumps require a lot of strength and balance.
And i'd put Layla and Tori(Tori over Layla, due to "dirty fighting") over Erynn and Alexis.
Last Cara and Iris(Iris also looks somewhat willing to fight dirty so she may take some of the bigger girls, not enough to go beyond "Layla class" however lol).
Brooke yet to be classified, but not upper tier surely.
