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 week leading up to the 2018 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 51 years ago.

Here is what we've covered so far:

7th Round | 6th Round | 5th Round | 4th Round | 3rd Round

We'll continue with the second round. Here's a look at who the Chiefs have drafted in the second round since 1967.

Notes:

• Forty of Kansas City's 42 second-round picks since 1967 have gone on to suit up for the Chiefs, playing in a combined 2,650 games.
• The Chiefs selected Pro Football Hall of Fame linebacker Willie Lanier in the second round (50th overall) of the 1967 Draft. Lanier played in 149 games for Kansas City, earning eight All-Pro selections and a spot in Canton in 1986.
• Seven of the Chiefs' second-round picks since 1967 went on to play in at least 100 games for Kansas City: center Tim Grunhard (169), linebacker Jim Lynch (151), Lanier (149), offensive tackle Dave Lutz (139), tight end Jonathan Hayes (136), offensive tackle Charlie Getty (119) and running back Ed Podolak (104).
• Though he only played in 23 games for the franchise before his untimely passing, running back Joe Delaney made his mark during his short time in Kansas City. Delaney rushed for 1,121 yards after the Chiefs selected him in the second round of the 1981 Draft – the most rushing yards by a rookie in team history until tailback Kareem Hunt broke the record in 2017.
• Another tailback drafted in the second round to make an instant impact for Kansas City was Christian "The Nigerian Nightmare" Okoye, who rushed for 4,897 yards and 40 touchdowns over his six-year career with the Chiefs.
• Nine of Kansas City's second-round picks since 1967 went on to represent the Chiefs in the Pro Bowl: wide receiver Dexter McCluster (2010), cornerback Brandon Flowers (2008), center Tim Grunhard (1990), Okoye (1987), linebacker Dino Hackett (1986), Delaney (1981), quarterback Mike Livingston (1968), linebacker Jim Lynch (1967) and Lanier (1967).
• The Chiefs have drafted more defensive linemen (9) than any other position in the second round since 1967.
