Kansas City Chiefs – Todd Blackledge
We’d love to be edgy and choose somebody instead of Todd Blackledge as the Chiefs’ worst player ever. However, it’s impossible given his record with the franchise and the context around it. Blackledge was a member of one of the most stacked quarterback classes ever after he won a championship with Penn State. Then he became the second QB to go after John Elway.

This meant that the Chiefs overlooked future Hall of Famers Jim Kelly and Dan Marino. These men evolved into two of the greatest signal-callers in NFL history. Meanwhile, Blackledge barely played for the Chiefs across five seasons with the franchise. He threw 26 touchdowns and spent most of his time as their backup (via Larry Brown Sports). The Chiefs spent the next several decades looking for a true franchise quarterback before they finally found Patrick Mahomes.
