Collier is a much more versatile player than the others you listed from what I have observed.
I actually rather like Napheesa. She seems like a nice girl and plays hard. I also believe she will get the Gabby Williams treatment in the WNBA. She's not big enough to play in the post, and lacks the ball handling and dribbling ability to play the perimeter. I'd be surprised if she had a breakout rookie year. Her body screams "wing", but she lacks the skills to play that position.
Compared to other players at her position, I believe that Diamond and Victoria are hands down better players. I'd even say Gabby is. If any current UConn player should have been on the training camp roster, it should have been Katie Lou. If they needed size, the senior twin towers should have been there over Morgan. She's had a very unremarkable pro career.
