Not that I really want to defend Holly, but in this case, I was thinking about it and I'll give it a stab.
Passion is not necessarily the same is intensity or fire. Intensity, fire, and other similar adjectives can be seen demonstrably on the court. Passion for the game, IMHO, far exceeds game time intensity. It encompasses players who are students of the game. Those who are truly passionate will spend extra time in the gym working on weaknesses. They will study game tapes, of them hoping to improve, or of others hoping to emulate. They will practice hard 99% of the time, encourage teammates, and be leaders in whatever way is comfortable for them (some are vocal, some lead by example).
Those are just a few examples of types of players who have "passion". Kids in general who love the game so much that they eat, sleep, and live for basketball. Passion also drives them to be better and to push themselves beyond what they thought they were capable of. Of course to get the most out of "passionate" players, you need coaches who "get it". Geno does, Holly does not. But my point was to point out that even Geno, to a degree, agrees with Holly.
Geno has lamented about kids "these day" on numerous occasions. They don't want to work as hard, are more invested in themselves, their style, their online presence (facebook, twitter, instagram, etc etc), have a sense of entitlement, and aren't as easy to coach. If that's what Holly meant (in general), I would say at least Geno probably agrees with her...
