A good way to think about it is this. The best women's basketball coaches are at the best Division 1 schools in the NCAA not in the WNBA. The best coaches earn the most money usually.
Tibbets earns $1.2MM, Hammon earns $1MM, Reeve earns $700k. Reeve didn't even win 50% of her games as head coach at Indiana State for several seasons, and she's considered likely the best coach in WNBA history.
Mulkey, Geno, and Staley all earn over $3MM per year. Even Jan Jensen earns about $1.2MM from us as an unproven head coach. Bluder earned almost $1.5MM her last few years.
Steph White was a pretty piss poor coach at Vanderbilt in her 5 years there, .357 overall and winning less than 20% of her conference games. In the WNBA she has a .600 regular season record and a .500 postseason record. For Indiana her salary isn't public but is estimated somewhere between $600-700k. Why on earth would we think she would be a mastermind coach compared to the many top college coaches that actually know what they're doing?
