Who are the 4? Do you mean Mathis, Flagg, Austin-Cave and Hyppolite? That would be a very good class, arguably as good as the guys we have graduating. But we need the final 2 (TAC and RH) to make it so.
Haven't seen them in games. But from the film, Hyppolite is my second favorite LB recruit Miami is after next to Flowe. And there's a lot of distance between those two and everyone else.
