Fair enough.
I'm not sure exactly what Fueled by Sports is, but that seems quite a bit optimistic. A guy who currently has grades of 55 or better basically across the board and projects to have 4 tools that are 65 would be the no-doubt, undisputed #1 overall pick. I don't think any of the most trusted national scouting guys/sites has grades like that on Ray.
The 65 on his fielding projection alone gives me pause. There is just about universal consensus on Ray that he will have to play LF eventually, and that's not what happens to a guy with a 65 fielding grade and a 55 arm.
Anyway, they still only give his speed a current plus grade, and even they give Lewis the higher ceiling.
