Statistical leaders don't always lead their teams to winning seasons. However, the numbers show that they pulled their weight regardless of their teams' win-loss records.
For some individuals, being a stat leader is confirmation of their skills. Tennessee Titans safety Kevin Byard logged 19 interceptions at Middle Tennessee State, but his eight picks during the 2017 season solidified him as a ball hawk and All-Pro. Someone just needs to tell Deion Sanders.
Some players rank among the leaders of box-score categories every year, which speaks to their consistency and value. Not surprisingly, most on this list are usual suspects.
