I went back through and watched each of the players mini-highlights focusing on the defense. A couple things I noticed were:
1. Isaiah Abraham is almost never the primary on ball defender in these highlights. Liam has 1 lay-up and gets a loose ball from him, and Youssouf gets a lob over him (but Abraham looks pissed at Tarris, I'm assuming Tarris switched his man off camera when he wasn't supposed to).
2. Hassan has very few highlights against him. Alex and Jaylin hit transition 3s over him, but that's it - except for Solo. Solo gets around a screen and hits a jumper, and then again gets by Hassan and hits a nice jumper off the glass.
Not sure this means much other than I have too much time on my hands, but if we think that Hass and Isaiah are going to be our 2 best perimeter defenders the highlights don't disprove that. Also, while Solo's highlights seem maybe a bit pedestrian compared to some of the others, he's doing some of it against Hass which makes it more impressive.
