I don't know if this is still the case, but a couple years ago, I remember listening to a podcast that talked about the culture of college football recruiting versus almost every other sport. It was specifically comparing basketball and football, and how in football, committing to a school really doesn't mean much. Coaches will maintain connections and still try to swipe a recruit if they can. Basketball, on the other hand, doesn't really have to deal with this. You'll see recruits decommit and change schools; but it's not very common, and it's looked down upon, to try and heavily recruit players who are committed.
