Thoughts:
When an expected starter appears in "dunking" videos [using term loosely] but doesn't start a game soon thereafter, it is unlikely to be an injury issue [and thus it is something else].
Starter is a misleading term. Maybe "finisher" is better or MPG players. Example: Manu Ginobili rarely started for the SA Spurs but generally played "starter" minutes and finished games. To get scoring off of the bench, Mulkey may start someone in place of Carrington. But expect Carrington to get the Starter minutes and finish tight games.
Richards has averaged the least MPG of Starter perimeter players each of the past 2 years. That is to be expected [energy expended defending best players and related foul issues]. If she now is expected to play more minutes and expend PG energy on offense, the D will have to adapt. Richards can't have the energy/foul issue of guarding small/quick PGs. Fortunately, Ursin is great on those players. Expect those players to overlap minutes to the maximum. That allows Richards to primarily defend the wing [her more natural defensive position] and allows Mulkey to give her time with the easier D assignment [using J. Oliver and Carrington to soak up D minutes on the tougher assignment]. Those changes are needed for Richards to average 33ish minutes per game.
Gusters will have to play when Baylor faces size [South Carolina, Oregon, KSU, etc.]. Will she earn minutes against more equally sized teams?
If Andrews can earn 7ish minutes per game that will be a huge plus. Ursin/Carrington/J. Oliver need to absorb [at least] 80-90 MPG collectively. Andrews provides "minutes flexibility" with every minute she plays. If Gusters isn't ready to go, Richards is going to be faced with spending some minutes defending the 4 [extremely "not ideal"].
Assuming health, no foul trouble, etc........expect Egbo, Smith, Richards, Carrington and Ursin to finish close games [unless J. Oliver makes a huge leap].
