the numbers. Pants changed from white to silver. The San Diego Chargers introduced new uniforms, changing their primary color from sky powder blue to royal blue. The helmets were also changed from white to royal blue, and the players' numbers on its sides were removed. In addition, the face masks were switched from gray to yellow. The Chiefs and Chargers were the first NFL teams to wear face masks in a color other than gray. Television ABC, CBS, and NBC each signed four-year contracts to renew their rights to broadcast Monday Night Football, the NFC package, and the AFC package, respectively. The major change was that ABC was also given the rights to the Pro Bowl, instead of having the game rotate annually between CBS and NBC. Don Meredith left ABC to join NBC's lead broadcast team of Curt Gowdy and Al DeRogatis in their own three-man booth. NBC also hired the then-recently retired quarterback John Brodie to replace Kyle Rote as the network's #2 color commentator, alongside Jim Simpson. ABC initially hired Fred Williamson to replace Meredith in the MNF booth, but he was so inarticulate during the preseason broadcasts that Williamson was replaced by Alex Karras for the regular season. CBS abandoned its pre-recorded The NFL Today pregame show in favor of a live, wraparound style program titled The NFL on CBS. Jack Buck was originally promoted to replace Ray Scott as the network's lead play-by-play announcer alongside color commentator Pat Summerall; only for CBS to shift Summerall from color commentator to play-by-play at midseason. Tom Brookshier was then paired with Summerall.
