McDermott looks like a 5* in that video. He didn't show much of that athleticism and skills in his high school highlights. His flexibility, balance and technique are superb.
Darling looks the same as he does on film. Massive frame and good athleticism but still very raw. His footwork was very sloppy and he doesn't understand how to kickslide properly or use his hands. Those are problems that can and will be fixed.
Bain looks good imo, considering the kind of prospect he is. He looks big, quick and agile which is all I want to see from him. He's very inexperienced and thus very raw, so I don't expect him to dominate just yet against good competition. The important thing to note is that his athleticism his translating to the field. Pass rush moves and functional strength will come to him in time.
I like Chad Thomas quite a bit. Pass rushing is effortless for hikm because of his long arms, body control and agility. I like Stacy Thomas as well but he's too small and our class is gonna be too small for him to be a part of it.
