For an NFL general manager to be successful, they really only need to hit on their Day 1 and Day 2 picks. Sure, if the team can land a couple of diamonds in the rough late in Day 3, it makes their talent evaluators look like the best in the business, but the overall success rate of sixth and seventh rounders is so low, that everyone is forgiven if those players don’t last long—or even to the regular season. Just use your best draft capital to the fullest, and you’ll stick around.
But we, as fans, love the underdog story.
