You can find shooting attached to bad players if you need it so desperately. There are always guys like Malik Monk or Tony Snell out there in FA or you could trade Cedi and a 2nd for Duncan Robinson. The lack of shooting in the Cavs lineup is an issue but I would put at least part of that on coaching. We have guys like Cedi and theoretically Windler glued to the bench because JBB doesn't want to play them and even when he does they just go stand in the corner instead of running curls or DHOs. Having shooters only matters if your offensive scheme doesn't reduce them to Amon Ones and Donyell Marshall in 2007.
I also expect to see improved shooting from our young guys. They are not sitting idle this summer and posting tons of open gym workout vids (looking at you ben simmons). Okoro and Mobley I expect to show more range and provide more spacing next year. Getting Collin back helps too.
Average to below average vets should never be a reason to not take a high upside player. If your young guy looks like he is the real deal, you send those guys packing and open up time to develop your young gun. If your vets are above average, you spend development time on your young guy and bring up to full speed in year 2 or 3. Portland has been doing the later for years and consistently churn out solid guys (Simons, CJ, even Nas Little). There are options, but Cedi Osman and Caris LeVert should not prevent you from taking a guy you think has even a 10% chance of becoming a difference maker or ceiling raiser.
I would have gone a different direction than Och at 14, but its not a terrible pick or anything. I have said this before, and I stand by it. The larger trend of recent moves is what worries me more than any specific trade. Between the way the other draft picks were used and the LeVert deal and honestly the JBB extension, I am worried we are losing sight of the big picture while chasing tiny goals. When you are optimizing your objective function, you don't want to get stuck in a local minima and I think we are focusing too much on that instead of the global trend.
