There was a period in the NFL, once upon a time, during which the Pittsburgh Steelers played such a relatively rare style of defense that they were able to regularly find quality pieces along the front seven in the late rounds.
The 3-4 defense was out of fashion for a while. Combine that with the fact that he played at an HBCU, Fort Valley State, and you get the biggest pieces of the puzzle explaining why a five-time Pro Bowler like Greg Lloyd was available in the sixth round of the 1988 NFL Draft.
A non-Combine invitee, he did participate in the Heritage Bowl, regarded as something of an HBCU All-Star game.
