Van Ginkel should be a good one. Great athlete, sound, instinctive, aggressive. Think he'll get a little bigger and stronger, and he's pretty much got what you want for that role.
I'm excited to see him play a bigger role. Likely upgrade over Van Noy, and in relation to the other OLB's in the class, he's much more suited for that role. Outside of Parsons, Collins, and Baron Browning, I don't see any natural fits for the position - maybe Ossai. Those are your options for competition with Van Ginkel imo.
When you're looking at Edge options for Miami, you're really talking about Shaq Lawson replacements/depth. So, you probably don't want anyone lighter than Oweh, and he gets by in part because of his length. My favorites relative to projections are Payton Turner, Cam Sample, and Elserson Smith. Basham also makes sense if he falls.
