Depends.
Miami right now is at 50% blue chip ratio. But, lacks 5-star talents. If Miami can close on these four and five stars...sure. But if they've got to dip in the 3-star pool and have a class weight heavy on 3-star types...no, its not a successful class.
I'm not sure if just getting Flowe on top of this pile is enough to say its a success, although, it does salvage it just a bit.
We still need WRs. It doesn't seem like any of the 4-stars are in the mix anymore...Marcus Fleming, Bryan Robinson, Darin Turner all still uncommitted and it seems we are looking at Doug Emilien over those guys.
I'm not seeing any high-grade offensive lineman in our close.
On defense...
Justin Flowe, Jaylen Harrell, Ruben Hyppolite (or recent offer Cooper, whatever), Keyshawn Greene, are mandatory if you are going to say this is a successful class. I'd like to say a 4-star+ corner is also mandatory for a successful class.
That would give us about 60% blue chip ratio. That'd be cool.
