Brittney Griner improved leaps and bounds while at Baylor. She was raw as a freshman offensively and turned into a powerhouse on both ends by her junior (and senior year).
Lauren Cox also improved leaps and bounds over her career after a slow start where she looked nothing like the #1 recruit.
Odyssey Sims also improved greatly while at Baylor, both as a PG and as a scorer.
Others include Nalyssa Smith, Queen Egbo, Kalani Brown, Alexis Morris, Kristy Wallace, Niya Johnson, and Sophia Young. If people are looking to discredit Kim as a coach, player development isn't the area to do it.
