While there are still four rounds left to go in the 2018 NFL draft, the reality is that there's a good chance the only rookies that are going to make an actual impact on the field in the near future are already on your team's roster.
Sure, there's the occasional late round steal that breaks out into a star or at least a starter. But the vast majority of players in rounds 4-7 won't end up making or breaking a draft class.
So that makes the end of Round 3 a good time to start assessing just how good a draft class is.
