I don't think that's true anymore. 2 years ago when HB/Huerter/Keegan were all 40%+, you'd have a point, but we're a flat out bad shooting team this year. Take away Domas and Keon, we're last place... by a ton.
Cam's also really developed as a passer the last few years and he's shown more on-ball scoring. But the primary directive; shooting, particularly from the wing slot, is a massive need.
Again, it depends on the price. Huerter+FRP+scraps is fine. Anything more than that or paying a "star" package for him is where you get in trouble.
