There was a lot of talent remaining on the board coming into Day 3 of the draft. For what the 2013 NFL draft class lacked in elite talent, it had in depth.
Normally only the top 100 picks are expected to become starters. Players in the fourth and fifth rounds are typically role players, special teamers or developmental projects. Players in the sixth and seventh rounds aren’t typically expected to contribute immediately, except on special teams.
A "steal" at this point is a bit different from what it would be in the first few rounds. There were several starters, early contributors and key role players that were steals on Day 3, and a lot of players have the potential to exceed expectations for their draft slot.
