He's really not an "athletic guard". He's a crafty, do it all kind of guy, with above-average athleticism. His athleticism is very similar to that of Vince Edwards, IMO, only in a 6'5-6'6 frame instead of 6'7-6'8. I wouldn't call VE an athletic forward... He can dunk with ease, but at 6'8 he should be able to. I'd call Carsen Edwards an athletic guard, and guys like OG Ananoby, G-Rob3, Branden Dawson, all athletic since that is where their hype is...
Can Eastern get up and dunk with relative ease? Damn straight he can. He won't blow by people on a consistent basis, and won't dunk every time he attacks the rim. I'd label him as a Michael Carter-Williams type of player, since that's his natural position. He can create his own, he plays solid defense, but his playmaking ability is where he excels.
