I like Hendricks a lot, but Ausar has a way higher ceiling (also a lower floor). Weaver said he was going for the home run swing and that's what he did. Day 1 Ausar is Hami with more height, length, IQ, defense, ball-handling, and passing. That's solid already, right? He's also a better 3 point shooter...but that's not saying much since he's at 30% compared to 27%, but there's hope. So, there's your floor.
But Weaver compared him to prime Andre Iquodala and that's probably a good comp for his ceiling. That's a lockdown perimeter defender, who can slash, play above the rim, be a playmaker for others, and shoot at a passable enough level to keep defenders honest. Adding prime Iggy to Cade, Ivey, and Duren would be phenomenal if he gets there.
The NBA is also moving towards having more and more ball-handlers and playmakers out on the court. Look at teams like Boston, Denver, Miami, and others who roll out lineups with 3 to 5 guys that can make plays with the ball in their hands. That's the biggest knock on Hendricks - he simply doesn't project as that type of player at all. So, while he's a nice roleplayer, he's also the kind of 3 and D guy you can get as a Free Agent or in a trade, whereas you can't get homeruns that way. Weaver is hoping Ausar is a homerun.
