I agree with you here- but my overall point is not that defense is entirely irrelevant, but that it likely won't be a huge important thing this year. (Or any more than any other year.) However, I would say that if there were teams with well thought-out defensive strategy, they will do quite well. (And I also know about the lack of functioning robot parts, from experience
) But I still for the most part think defense will be rare, and good defense will be even rarer, because teams with a well-thought out defensive strategy are probably good enough teams that they will be able to score with consistency.
