Again I completely disagree, all the players switch on defense at Uconn, who guards who is not an issue unless Geno decides that there is a player on the other team that needs special attention when he goes to Williams or Nurse. Yes Williams and Collier usually play closer to the basket as both Nurse and KLS are playing guards spots because of their skills. KLS has shown she can easily post but she has skills that the other players don't on the perimeter that opens the floor for them. When KLS posts the question is who passes the ball, the only other good post passer is Williams, so you see Collier benefits from the skills of both Williams and KLS along with Nurse on the perimeter and Chong, not the other way around. Collier is open as she is the third or fourth option of the defense or you are saying every coach that Uconn has played against is an idiot
You are talking theoretically about what you think might happen. I am talking about what actually happens in the game.
1) The reality is that KLS rarely posts up. In fact, in the last three games she only scored 4 baskets when she posted up -- that is she went to the blocks and received a pass (not counting fast breaks or drives) -- yes I chart some of the games. As much as you want to posit that KLS posting up is a significant part of the offense it just isn't yet.
2) Yes, they switch on defense. But their basic defense keeps KLS, Chong and Nurse out of the paint guarding the other teams bigs, except when they go zone, then KLS can be anywhere (as can Gabby and Napheesa). Next game count how many times you see KLS on the other team's center in the blocks (as opposed to at the foul line after a pick). Not much if at all.
3) How in the world is Napheesa the third or fourth option on offense? Your fourth option is your second leading scorer (one point off the leader)? Your third or fourth option has taken the second most shots (by more than 40 over the next player)? Your third or fourth option leads the team in field goal percentage? So if all that is your fourth option you better get options two and three moving. Second, UConn runs, for the most part, a type of read and react offense. Without spending the next three paragraphs breaking it down, it does not have a first option, second option, third option, fourth option, fifth option. They have a bunch of options they look for: a back door, defenders going under the screen, players establishing position under the basket, a curl around a screen, etc. It really depends on the defense, how the offense reads it, who is hot or has a mismatch, etc. After looking for the first option the rest is reading the game and the defense. That is why it is (with movement and good spacing) so hard to defend. The defense doesn't know which "option" the team will follow and neither does the team until the play unfurls. That is why Geno's constant refrain is "figure it out". Because that is what this offense requires.
4) They all make each other better. That is why they are winning. So what is your point? That Napheesa benefits from the play of Williams, KLS, Nurse and Chong? Okay, I agree. Just as they benefit from her.
There is a reason the Kara Lawson keeps bringing up Napheesa as a potential POY candidate and it is certainly not that she is the fourth option. Or if she is the fourth option, she is the best fourth option women's college basketball has ever seen -- a fourth option that, as a sophomore, scores 19 points a game on 65% shooting. In that case, give me a team of fourth options.
