^ after Monk was hurt Foley played a whole lot on the OL, so that was four strong contributors. Obviously Elko can recognize talent..finding Burns from Cornell, Foley from Holy Cross, Harris from Arkansas State, and Lyttle (Colorado).
Then add in Dillon who played very well at LB, from Columbia...I would expect that Duke is seen as a more credible destination at this point...
I've noted that Davis, Harding and Shelton have played quite a bit less as the season wore on, so I'm not surprised they are portalizing...as you say, best of luck to them.
