I don't know them, but I'd guess that not a single guy on the WBB practice team is a D1 level talent and D2 (and maybe even D3) might be pushing it.
You do know that Geno limits what the practice players can do, correct? They are given roles to prepare the team. It isn't a pick up game. Think about that minute, guys who likely could not play college ball must have restrictions on them to play against the best WBB program in the country. Doesn't that really tell you everything you need know about their relative capabilities?
No, it tells something about size and strength. None of the women's male practice players could play Div 1 or Div 2 basketball in my opinion. I do believe some could play Div 3 though. Again, just my opinion having seen a number of practices.
