First, it's too early to grade anything/anyone in the draft. No one knows the answer and pretending to know is a sign of delusion. Second, grades are like rankings - they're fun exercises but of little value. In all due respect to some here and to 'experts' who do that stuff for a living, the only grades that matter are those given by the 32 teams. If I had to make a decision based on ranking, I'd follow VJ before I'd follow Mando, Omar, or those here (not saying those here resemble Omar or Mando). Just look at rhe '16 draft and compare published ranking to the draft results. A number of teams selected players waaaayy before their ranking. Were they 'wrong' or was their ranking different? Pick any R2 prospect and find their highest/lowest ranking. Who's right? For me, Gase and VJ have their rankings, spice it up with scheme fit, personality, needs, prototype, and adjust the rankings accordingly, as do all teams. Trying to grade a draft this early and without knowing the outcome (particularly this soon after the draft) is fun. It's opinion. It's a mental exercise. But pretending it has value is based on perspective.
