On December 16, 1973, NBC cameras were there to cover O. J. Simpson as he rushed for 2,000 yards in one season. On that particular day, Simpson's Buffalo Bills would go on to beat the New York Jets at Shea Stadium. Two days before he was assigned to call 1973's regular-season finale between the Houston Oilers and Cincinnati Bengals, Bill Enis died from a heart attack at the age of 39. Al Michaels was brought in to replace Enis in the booth with Dave Kocourek. 1974 would mark the final season for what would be Al Michaels' first stint with NBC. That season, Michaels called six-tier games with Mike Haffner. Also in 1974, Don Meredith would come over to NBC from ABC's "Monday Night Football". He would join Curt Gowdy and Al DeRogatis for the playoffs and Super Bowl IX. He also worked that year's Thanksgiving game between Denver and Detroit. In Week 13, he joined Jim Simpson and John Brodie to call the Cleveland-Dallas game.
