From the video

Mahomes is 22nd in completion rate against man coverage. He's 27th in yards pass attempt... The success rate for the Chiefs recently has been way down... the Colts don't have a good pass rush and without the forest Buckner it's a little worse whereas the two teams that Mahomes just faced obviously Broncos bring a lot of heat
STACKED’s take
Elite Colts secondary presents challenge, but weak pass rush could enable completion volume.
Mahomes faces significant matchup challenges vs. Colts elite secondary in Week 12; he ranks 22nd in completion rate against man coverage and 27th in yards per attempt against man. Recent success rates have been poor: 13th percentile vs. Bills and 22nd percentile vs. Broncos. The source expresses concern about stop-start offensive rhythm against an elite secondary, especially if Colts employ heavy man coverage schemes. However, the Colts lack a good pass rush (especially without Forrest Buckner) compared to the Broncos and Bills, which could allow Mahomes to throw a bunch of completions to Rice and Kelce, similar to how Jacoby Brissett had high completion volume last week despite middling EPA per play. This completion-heavy game script should benefit Mahomes' fantasy output.
