Perhaps this is a larger discussion about team building, but I do believe it relates to draft prospects, especially in the Cavs case since we do not have a core moving forward and the draft will (hopefully) provide that..
The one thing I've started to believe is in order to be a competent, successful franchise is you need your 2-3 best players to be very good two-way players... At worst, 2 of your top 3 or 3 of your top 4 to be successful two-way players..
Yes offense is en vogue and will continue to dominate the modern era, but the best teams still have good enough defenses and can get a stop when necessary...
We lived this out in the Cavs era, but if your top players aren't good two players, it's hard to hide them and the lack of attention to the defensive end, trickles down and the results come accordingly...
You look at any of the top teams: Raptors, Thunder, Warriors, Sixers, Bucks, Celtics, etc., their best players are all two-way players...
The only caveat is if you're not a two-way player, you have to be really damn good offensively (Kemba, Harden, Lillard, Kyrie, etc.) to overcome any defensive deficiency to become a core piece...
Even if you're a good or solid offensive player, but not good enough to make up for any lack of defensive ability, it kind of gets in no-man's land and it's hard to become a productive, core piece that way... Unfortunately, we're seeing that to an extent with Sexton right now...
I think that's why you've seen former top-10 picks like Kanter, Barnes, Turner, Monroe, Brandon Knight, Dion, Jabari, Julius Randle, Okafor, etc., kind of bounce around and not really find a true home/role because their offense never developed to the extent it covers for their defense...
Look at the NBA's top-40 players according to RPM wins: only 4 players have a negative DRPM, to which those are Curry (who can be a decent defender), Lillard, Kemba and Doncic (who might become one in time)... You guys have who hover around 0 but those guys are your truly elite offensive options, which largely upholds any value they have...
Go back to last year's RPM Wins top-40 and you have 8 players: LeBron, Lillard, Kemba, Durant, Middleton, DeRozan, Beal, Dinwiddie and Tobias Harris... In large part, we know Durant and LeBron can be very good defensive players, the effort just isn't consistently there at this point in their careers...
Regardless my point still stands: two-way players are very important, and probably even more so in today's game... And it's extremely important to be cognizant of this when drafting high and drafting potential "core" players...
So why does this matter?
I believe it's why Zion is far-and-away the best prospect, without a doubt, and why you might give pause to someone like RJ Barrett--unless you think his offensive potential is so far superior, it will vastly outweigh any defensive issues...
I'm still going through other prospects and what it would look like if the Cavs don't get Zion or, even if they do then how careful they need to be in shaping the core and using high value assets on certain player skillsets...
