4. Rich Jackson

Years With Broncos: 1967-1972 (6 Seasons)

Stats: Defensive statistics not yet recorded

Career Accolades: 3-time 1st-Team All-Pro; 3-time Pro Bowler

With Rich “Tombstone” Jackson, as well as several other players on this list, it becomes difficult to compare statistics because prior to 1982, the NFL didn’t officially keep track of sacks, and it took even longer to keep track of tackles.

So when you go look at Jackson’s career statistics, you’re going to see a whole lot of blank spaces.

Jackson, though, was one of the best pass rushers of his generation; he was named 1st-Team All-Pro three seasons in a row (’68-’70).

The only thing holding Jackson back from being higher on this list is that he only spent six seasons in Denver.
