I read the article and I'm not sure Tyler really is interested in Duke other than perhaps to be able to say he was offered by everyone. Rivals lists five schools UCLA, USC, Arizona, Louisville & Michigan State of interest. And to be blunt none of those five are exactly Ivy league if you catch my drift. I'm sure Watzone or Sumner can give more detail. Sounds like a good guy and a great player. But odds are the Duke staff already knows of him and has other plans for whatever reason.
For what it's worth three of the remaining five players in the top 10 list Duke; Smith, Barnes & Knight. All of which are rated higher than Tyler.
