Matchups We Love
Patrick Mahomes looked good in his first game back from a torn ACL. He finished with 22.7 fantasy points behind three total touchdowns (two passing and one rushing). Mahomes now gets a matchup against a Colts defense that just let Jackson throw for 324 yards last week. The Chiefs quarterback is a solid QB1 play this week.
RB Kenneth Walker III
After last week's big fantasy game, Kenneth Walker is a must-start RB1. He totaled 191 yards from scrimmage with two touchdowns while finishing with 34.1 PPR fantasy points. To make matters even better for those who own Walker, he will now face a Colts run defense that gave up 144 yards and three rushing touchdowns to Henry in Week 1.
Kenneth Walker III Week 1
- 69% snaps
- 23 carries, career-high 173 rush yds, TD
- 15 routes, 6 targets
- 3 catches, 18 yds, TD
- 34.1 fantasy pts - RB2 on the week— Michael F. Florio (@MichaelFFlorio) September 15, 2026
WR Rashee Rice
Rashee Rice was almost a non-factor in the passing game last week. He caught both of his targets for 19 yards and one touchdown. That low target share isn't what Rice is used to. Nevertheless, the 26-year-old could be a much better fantasy option in Week 2. The Colts gave up 150 yards and one touchdown to Flowers in the slot last week. Rice, who plays primarily in the slot, could see more opportunities than a week ago.
Matchups We Hate
No, you're not sitting Jonathan Taylor just because he lands in this section. Every fantasy manager should continue to start Taylor as an RB1 in all formats. However, this is a tough matchup for the former All-Pro running back. The Chiefs allowed the seventh-fewest fantasy points to opposing RBs last season, and held Denver's RB room in check last week.
Other Notable Matchups
QB Daniel Jones
Jones did not play great in his first game back from an Achilles injury. He will now go up against a really tough Chiefs defense. Therefore, Jones will come in as a low-end QB2 in Superflex formats for Week 2. It is a bit concerning for his fantasy value that he only ran one time for four yards in last week's loss.
Colts WRs
Update: Pierce will play in Week 2
The only WR that fantasy managers can trust right now is Alec Pierce. Pierce finished with 10.1 PPR fantasy points in Week 1 and was the clear top target in this offense. But his status for Sunday's game could be in jeopardy after missing both days of practice to kick off the week. If he winds up playing, he'll be a low-end WR3.
As for Josh Downs and Keenan Allen, it's best to sit both WRs this week. Downs only caught two passes for 37 yards, and Allen chipped in six passes for 32 yards. Those two WRs will likely split a lot of the short passes from Jones, which hurts both of their fantasy values. Downs is a lower-end flex play, while Allen is unstartable.
TE Tyler Warren
Warren will remain a solid TE1 play this week. He caught a touchdown pass in the Colts' opener, and the Chiefs let Evan Engram tally four catches for 43 yards and one touchdown against them a week ago. Warren has become a safety valve for Jones in the middle of the field since the start of his rookie season last year.

TE Travis Kelce
Kelce's fantasy day was salvaged by a long catch and run last week. Other than that, he really didn't do much in Kansas City's passing attack. He'll still be a TE1 play this week after his three-catch, 71-yard performance. He's a high-floor tight end option in a game that has a higher over/under this week.
