I think there are more guys who can be ranked high, but fly under the radar or aren't "big names". Examples are Eric Reid, Chris Faulk and Kevin Minter. All 4 star guys, but not discussed much. I think Diarse and White will be those guys this year. IMHO
I see all of this completely differently. Guys that fly under the radar usually are 2*s or not even evaluated by any scouting sites (Rivals, ESPN, etc).
I understand guys may not be 'big names' compared to Nkimdiche, but still big enough to get a rare 4* honor and be committed to an elite program.
