Top 10 worst Denver Broncos quarterbacks: Should Kyle Orton be on the list?

Kyle Orton.

After Sunday's humiliating defeat at Arizona, the Broncos are at 3-10 -- a mark that recalls the horrific '60s and early '70s. And since Kyle Orton is suddenly playing down to that level, we thought it was the perfect time to revisit our slideshow of the most mediocre quarterbacks in the franchise's half-century of existence.

Should Orton join the list? Decide for yourself below.

Mickey Slaughter.

Mickey Slaughter played for the Broncos from 1963 until 1966, chalking up a completion percentage of 49.8 and a per pass average of 6.2 yards. Impressive.

Jacky Lee.

Jacky Lee wore Broncos orange in 1964 and 1965, completing more than 50 percent of his passes each year. Too bad the team stank anyhow.

John McCormick.

John McCormick came and went from the Broncos starting lineup. He has stats with the squad from 1963, 1965, 1966 and 1968. Career completion percentage: 38.6.

Steve Tensi.

Steve Tensi played in the majority of Broncos games between 1967 and 1970 -- and , not coincidentally, the team lost most of them. He had 43 career touchdowns -- and 46 career interceptions.

Steve Ramsey.

Steve Ramsey played for the Broncos from 1971 to 1976, sometimes as a backup, sometimes as a starter. He did less damage on the bench, and it wasn't until he was supplanted by former Cowboys QB Craig Morton that the crew finally began to reach its full potential.
