You are exactly right. Oscar takes up way too much space under the basket which prevents cutters from going to the basket. If is a team is going to be successful playing the post with his back to the basket, he better be dominant in his position otherwise he is more hurtful than helpful.Idk if Cal wants him to. Which is crazy bc he is the NPOY and dominates the glass. But Oscars style isn’t cohesive to how Cal likes to play defense. You need a super athletic 5 that is capable of guarding the 3-5 super effectively and is sufficient at staying in front of a 1 or 2 but giving a little space to make them think about shooting over.
Cal needs an AD/WCS type at the 5….or play 2 physical, athletic, 4s together like he did at Memphis a few times. Ppl focus on shotblocking (which is nice if tou can have both) but Cals defense hinges on switching and strong hedges and not giving up a major mismatch when your 5 gets switched off on guards
