I guess it depends on if the scouts believe Kelsey will be able to score in the WNBA like she did in college. She reminds me of Jackie Stiles, who got her points in the WNBA but at a much lower efficiency compared to her college days. Kelsey plays smart, but she's not very big or quick. Not sure if she will be able to replicate her performance in the WNBA.
I think Kelsey will be a serviceable pro, but I think that enough WNBA GMs will be infatuated with Diamond's athleticism that she probably is a more popular top pick. In either case, I think it's a certainty that those will be the top 2 picks.
