1. All prospects have risk
2. There are more All-stars in baseball than 70 grades given out by FG's by nearly 20 times.
3. Scouting should try to be right, not cautiously optimistic
4. It's OK to be wrong about a guy and evaluators need to get over that fear.
5. Robert is a 55 on FG; so he's no where near a 70.
6. Every prospect has concerns, and in what world does Robert have a .310 OBP? He is projected for a .317 (still low) but he was running 340-380 last year. And yes, no prospect is perfect so Robert deserves a 70; his ceiling is elite.
70 isn't too high for generational tools. This thought process that if he doesn't pan out, then my grade looks stupid is naive. Luis Robert is projected to be a 3 WAR player in the MLB as a 22 year old rookie; if that's not a 70 talent, then nothing is. It's one of the rosiest projections for a prospect I've seen.
