Edwards bigger than Kemba? I do not think so.
If when you say “bigger”, you mean “taller”, then officially Kemba is one inch taller. But it’s also true, again officially, that Edwards weighs 15 pounds more. That’s substantially bigger.
Carsen is built like the proverbial fireplug. At the same time he’s got explosive acceleration; this guy was made to play on-the-ball defense at the point of attack.
Official heights can be very misleading ...
That’s why I added “official”; and in fact there are other variables than the ones you mention, including how it’s done, who’s doing it, how upright they stand, and even what time of day it’s done (most people are shorter in the morning).
The exact numbers aren’t that big a deal, in my opinion. I wanted to push back on the idea that’s out there that Edwards is a “waterbug”; he’ll be hard to muscle on defense because of his weight and lower body strength, while his height is in the same neighborhood as those other guys (except IT, of course).
So, is Carsen IT with defense? Well, even IT wasn’t IT when he first came into the league, so even if Edwards really is All That it would be an achievement for him to crack the rotation in his rookie season. Having said that, Terry Rozier is gone now, and there is no one in front of Edwards for that job.
It looks like a good bet that Carsen can shoot with range off the dribble, can create good shots ditto, can dribble drive with either hand (love his hesitation move), and will probably have a decent floater for when he can’t get to the rim (looked a bit...
experimental in SL, I thought, even when it went in, but let’s be optimistic and say that he’ll just need more reps).
Now you can always count on someone waiting in the wings to tell you, “Summer League is meaningless!” - and there’s a grain of truth in that, too, especially when it comes to shooting and rebounding. 3-pt%s are notoriously variable, anyway, even without all the open ones and changing lineups you get in Vegas. So .467 from the arc seems highly unlikely when he gets to the NBA. But having said that, he won’t have to create everything off the dribble in the NBA, and given his skillset you could imagine a fair amount of his minutes playing off the ball - with Marcus Smart, for example - and getting higher % catch-and-shoot opportunities.
But in the end it’s defense that will get him in the rotation. It might be premature to predict that he’ll be able to create and make shots like Isaiah did; but it’s not a stretch to predict that he’ll quickly surpass IT as a defender.
