All we can do is go by the information that is available to us.
According to 247 D'ohno is given credit for the commitment of Nick Linder. His remaining top target that isn't currently committed is Anthony Moten.
Some other top targets that he was the primary recruiter for that are committed elsewhere are: Jabrill Peppers, Corey Holmes, Chris Lammons, Kiy Hester, Ravian Pierce and Marquese Dudley-Gordon

James Coley on the other hand has the following commitments credited to him: Bethel, Rosier, Trayone Gray, Kayaa and Yearby. Those are the prospects that he was the primary recruiter for. It does not include prospects for which he was their secondary recruiter (Chad Thomas the only one committed he's credited with being secondary).

All ranked nationally top 30 for recruiters according to 247. I'm not sure how accurate and up-to-date this information is, but it's all I have to go on. Don't tell me coordinators aren't heavily involved or relied upon in recruiting, because they are...if they're good at it.
