The winter sports scene here isn't nearly what it is up there. From what I have seen there is a round ball contingent in the larger metro areas, and even in some of the big schools where I live (Waco area), but their popularity overall does not hold a candle to football and baseball, the #1 & #2 boys HS sports in TX. At my kids school, basketball was viewed by most as a tool for maintaining conditioning between football & baseball/track, which IIRC start practicing in Feb. Heck, there's not a school in this area that even offers wrestling! Also, if I'm not mistaken there is an overlap in seasons. My youngest graduated in 2018 so I'm starting to forget some of these details.
My perspective comes from small/medium sized school experiences. @foxbat might be able to provide a better read on the large school winter sports scene, having lived in the Houston area IIRC.
