Reggie Bush was the No. 2 player in the 2003 recruiting class (Rivals), one spot ahead of fellow USC signee Whitney Lewis. Three years later, the two-time All-American and 2005 Heisman Trophy winner, was the second pick in the 2006 NFL Draft. Lewis, who later transferred to Northern Iowa, wasn't drafted in 2006 or any other year. Entering the 2019 draft, Lewis is one of 10 former top-five picks to go undrafted.
Since Rivals began ranking high school recruits in 2002, more top-five recruits have gone undrafted than been top-five picks in the NFL Draft. In 2018, none of the top-five picks were former top-five recruits, nor were any in 2016 or 2015.
Of the 66 former top-five recruits who've been eligible for the draft (not including Rashan Gary and Byron Cowart in 2019 or 2011 supplemental pick Terrelle Pryor), 10 have gone undrafted and only seven have been top-five picks. Both groups could grow this year if Gary is a top-five pick and/or Cowart isn't drafted.
