The model for the one and done scenario should be 2011, IMO. Have a junior-senior laden roster that is a top 10 team on it's own, but recruit and sign 1-2 very elite one and done players to push them further ahead- like that team did with Irving.
I've always felt that the one and done players should not be creating their own locker room and culture at Duke. They should be entering a culture which has been well established by the experienced players (that actually fucking play and can score) and coaching staff. I think recently, last season in particular, that the "one and done culture" kind of swamped the team. Tatum and Giles were for sure leaving- Kennard and Allen were possibilities, Jackson and Bolden came into the season wanting to go pro.
We need to do a better job of blending one and done's into the program, and we probably shouldn't be signing 3-4 a season as that will make it extremely difficult to "blend them in". Right now, we are borderline Kentucky. I will say that I don't think we are entirely there yet as we have still relied recently to a great extent on players like Amile Jefferson, Kennard (two years), Allen, Quinn Cook. But, it really feels like we are about to become Kentucky, and I don't want to become that. The best strategy to the one and done game is to have established veteran players, and then compliment them with 1-2 elite one and done players.
When I say elite one and done players, I mean players that will be extremely productive and considered among the best freshman in America. I don't consider Frank Jackson or Marques Bolden (Bolden isn't one and done but he sure wanted and expected to be) an elite one and done. I consider Tatum to be. The Giles thing was just unfortunate but he fit the mold of elite.
To summarize, I want to get away from having to recruit waves of "one and done" freshman to bring in a new wave of talent and to plug roster deficiencies. If the coaches correctly evaluate 3-4 year players we wouldn't have to bring in a new roster every season, and instead could focus on the really elite couple of guys that will enhance the roster and take it to the next level. We are basically just recruiting talent at this point, instead of trying to balance recruiting talent and how that talent fits. Last season's roster was frankly a bit of a mess, and I refuse to believe there was ever any real plan for this current recruiting cycle on what the "plan" was for this upcoming season's roster, style of play, etc. We just recruited talented and are now adjusting on the fly. It's a risky game and that shit catches up to you overtime.
