The wild card for me is Kaminsky. Yes it’s preseason but he was the most consistent offensive player on the floor. I could see him playing more than 7mpg. Easily. I think there is even a chance he could legit compete with Saric for starting.
I'm not a fan of Frank, but I'm leaning closer to what you're saying. He played really well (Offensively only) in preseason. Not just shooting, but ball distribution and maintaining good flow on O. Saric is far from proven as a starting 4, so I could see why Frank could steal some more of his minutes. But Frank is an absolutely awful defender. And we already have one of those guys starting at SG and two averageish Defenders at SF and C. Saric is at least "not awful" on D, which is why I'd still give him the majority of PF minutes.
