I think it's probably the case that Clark has the highest combination of motor, grit, and talent in D1 WCBB right now. I think there are players on some teams who have more of each (motor, grit, or talent), but she is kind of the nexus of all three.
I suspect a bit of the skepticism is that buffo states like that don't usually translate into a really effective team. In theory, the person with the most assists shouldn't also have the most rebounds, points, trips to the line, and steals. That's just not an effective allocation of playing time.
And I suspect what the homers are reacting to is that Bueckers has almost as much motor, about as much grit, and arguably more talent, and does that all while getting her teammates more involved. So when folks start saying "Cait the Great!," it's natural to hear an implicit (and unfavorable) comparison being drawn to Bueckers.
I think the counter to that is, well, Clark doesn't have a starting line-up of fellow top 5 recruits to play off of. And it's a fair point.
I guess in the end I'm coming to the same place I came to with Sabrina Ionescu, and, to a lesser degree, Kelsey Plum. Could be more effectively deployed, and probably has a ceiling on how far her game will go, but really fun to watch, and great for the women's game to generate more attention and respect.
