@HoopDreamsmag has a feature story on 2013 6-7 F Gabe Levin, who is now receiving interest from Duke and Michigan (although the story only references Duke). Looks like he didn't get any D1 offers in high school, so went to prep school for a year at St Thomas More. Currently committed to Hofstra (with a GW offer) but sounds like he's reopening his recruitment.
Btw, I love getting recruits who spent a year at prep school (McGary, Stauskus, Albrecht). That one year makes a huge difference in size/muscle and makes it more likely that they can contribute immediately. It leaves the player with four years of eligibility but pushes the four years back, allowing for more physical (and hopefully mental/emotional) maturity.
