Haven't watched the video but I wonder if this is more for help defending human players who are really good on the sticks offensively. Defending the computer is one thing but defending someone who is skilled and may have mastered the new offensive controls can be challenging.
For those who haven't heard of Sam Phan before I highly reccomend watching his videos. Whether you are a beginner or an experienced 2K player he will give you tips to improve and solidify your skills. Some of his tips are basketball knowledge based but other strategies are more based on how to execute things in the game. His video on crossovers is definitely helpful for those who are struggling with adjusting to the new dribbling controls and getting by defenders 1 on 1
