The key phrase is when he says, "...and let her coach."
That's the problem...lack of evidence of actual coaching that's taking place.
When the team looks utterly confused & in near-total disarray on the floor...and the head coach makes highly questionable substitutions, doesn't make strategy adjustments (both offensively & defensively) that should be obvious, and basically acknowledges that she doesn't know how to motivate the team...
there's a problem with the style of "coaching."
And...if the problem is with the players, then that goes back to recruiting. Apathy and/or lack of effort doesn't seem to be a problem for most other top-tier (or lower-tier) programs.
Likewise, when you whiff on the recruiting trail, that's part of "letting her coach," too.
No one's denying that Warlick has made major contributions both as a player and assistant. And had taken top talent and won MOST of the games in which the LV were favored based upon talent alone (as in, 85% of the schedule). No one's saying that she isn't a decent person or even a fine second-chair. But the offensive woes stretch back decades, and CHW hasn't shown any upgrades in offensive strategy.
The question has been asked...and it's a fair one..."Which major college women's program would want to hire CHW as their head coach" (due to retirement of their coach or need to rebuild in a hurry). Smith suggests that she's at the top of her profession & asks who could do better (for starters, Texas's coach has owned the LV the past two seasons even while improving each year over the same time span as CHW's tenure...going from unranked to becoming a top ten team (with more talent on the way). Smith should consider the question of who would even be interested in trying to lure Warlick away from UT if the situation arose (and given that her current salary would make her a bargain catch).
She's got the rest of the season to prove that she can make the proper adjustments, figure out how to motivate, and convince some top recruits that they will receive the proper coaching at UT. With the talent available including two of the top-ranked players in the country, Smith shouldn't be so naive as to expect that fans will just accept mediocrity.
