Most of your post was inoffensive and even uncontroversial, right up until that zinger in the last sentence. I can't speak for the others, but what I don't like is throwing a bald assertion such as that into the end of your post (knowing "people on this site will not like this"), and not presenting evidence or reasoning in support of it. If that is your view, then on what evidence do you base that view? Since you didn't say, even in an otherwise verbose post, we can only guess what you are thinking.
You are impressed with Becky Hammon, and perhaps you may feel that the NBA-style offense that she has brought to Las Vegas is where the game has moved on to? Yes, the Aces take a lot of 3-point shots, which is logical for a team that has Kelsey Plum, Jackie Young, and Chelsea Gray in their starting lineup. NBA teams these days also do that -- I read somewhere that 45% of shot attempts in the NBA are 3-pointers. Even so, I think Geno (not to mention a number of less gifted coaches in the college and pro ranks) would be capable of figuring out that when you have that kind of talent on your team, that is probably where your offensive advantage lies.
I think that there are other coaches in the WNBA who are, for practical purposes, as good as Becky Hammon. I am thinking specifically of the Chicago Sky coach (sorry I'm not recalling his name now), and the Connecticut Sun coach, Curt Miller. Neither of their teams relies on 3's to the same extent as Las Vegas, but that's because their strengths lie elsewhere. The Sun in particular are a front-court dominated team (as the Aces used to be when they had Cambage), so they don't take or make nearly as many 3's as Las Vegas. But I don't think that any of these three top WNBA coaches would or should use the same strategies if they were coaching top-level college teams, because even the best college teams don't have the same concentration of talent as the best WNBA teams.
I'm not saying that Geno's basketball knowledge is immune from obsolescence. It would not surprise me, for example, if Sue Bird (or Miller or Hammon) knows some X-and-O stuff that Geno is not aware of. But there are very few people (and no current college coaches including Kara Lawson or Lindsey Whalen) who would fit into that category. Certainly Dawn Staley, despite her recent success against Geno, is not a match for him at the X-and-O level, any more that Muffet McGraw was in 2013 after she won 7 of 9 games against Geno. Dawn and Muffet won with better talent, not with better strategy or game planning.
But here I am refuting arguments that you didn't make, because you didn't make any arguments. You just dropped that compost at the end of your loquacious post, knowing it would irritate people, and not developing your reasoning at all. Or did you have any reasoning?
