You mean Monday night? Chiefs vs Broncos?
Usually Sean McDonough and Jon Gruden do the play-by-play telecast. Although not a huge fan of McDonough and Gruden - they aren't the worst. This game was, for the most part, an absolute snooze fest. Trevor Siemian has 10 touchdowns versus 9 interceptions through 7 games, with a 76.8 QBR. Their defense isn't near as great as it used to be, and they've managed only one lone win against an above .500 team through 7 games this season.
I think Al Michaels and Cris Collinsworth (NBC) do a much better job. Collinsworth (imo) is the best tv analyst in the business.
Not a huge fan of Nantz, although Romo has helped the CBS telecasts somewhat.
Off topic a bit... looks like there's more layoffs coming at ESPN. Not sure anyone at the network feels safe, given the lopsided direction they seem hellbent on maintaining. ESPN has never been more irrelevant in sports imo... Fox Sports is kicking their asses. And then some.
