There's a significant likelihood that this will be the first post-OAD year (since OAD was instituted). Duke looks to be in the mix for top recruits like RJ Hampton and Isaiah Todd, but I expect we'll see both go pro straight from HS.
From what I can tell, we're also looking at Nico Mannion and Jeremy Roach. Scottie Barnes is another name I've seen mentioned, but he's a top 10 recruit.

This may be a seismic year in recruiting, particularly if K retires.
