I have no idea why Vann left. But, the Vann girls don't strike me as the types that would run from competition. Tough minded kids it would appear to me from the outside looking in. Maybe she didn't get along with Jennie, or wanted to play point, didn't like Chavez or another player, or was mad we didn't recruit her little sister. Only the Vann family would know for sure.
If we don't lose any other players to the portal, I like the look of this team. Particularly if we can land a couple players at certain positions out of the portal.
If Parks can reliably shoot the 3 and handle the ball under pressure, then she can help the team/cause.
