A system called the "common draft" was implemented for the AFL and NFL in 1967, creating a joint draft between the two leagues and establishing the precursor for what has become the marquee event of the offseason.

The two leagues merged in 1970, and the rest is history.

Over the next several weeks leading up to the 2021 NFL Draft, we're going to take a look back at who the Kansas City Chiefs have selected in each round since the event's beginnings 54 years ago.

Let's begin with the seventh round, where Kansas City does not currently own a selection in the upcoming draft. The Chiefs traded into the seventh round last year to select cornerback BoPete Keyes with the No. 237 overall pick.

As if now, these are the selections Kansas City currently has for the 2021 Draft:

No. 31 (Round 1)

No. 63 (Round 2)

No. 94 (Round 3)

No. 136 (Round 4)

No. 144 (Round 4)

No. 175 (Round 5)

No. 181 (Round 5)

No. 207 (Round 6)
