I'd go for Becky Hammon. Runs the fastest tempo and highest efficiency offense in the WNBA, also the highest efficiency defense. Sat next to Popovich for 9 years, then after getting passed over for NBA gigs went to the WNBA and had the league's best record two straight seasons and won two straight titles, going 16-3 in the playoffs.
They won't hire her, but she's the right person for the job and where the list should start and end.
