1. Allen Bailey is off to the best start of his career

Through six games, Bailey has already picked up 4.5 sacks, which is just 1 shy of breaking his single-season best of 5, which was set last season.

2. If Landry Jones is the Steelers starting quarterback…

Jones had a passer rating of 149.3 in his NFL debut against Arizona last week, completing 8 of 12 passes for 168 yards with 2 touchdowns, marking the second-highest QB rating in NFL history by a player in their regular-season debut.

It's unclear if Ben Roethlisberger (knee), Michael Vick (hamstring) or Jones will get the start.

3. Steelers wide receiver Martavis Bryant coming off a big game

Bryant led the team in receptions (6), yards receiving (137) and touchdowns receiving (2) last week.

His 137 yards receiving are the second-most in a single game in his career (143, Nov. 9, 2014 at New York Jets) and his 2 touchdown catches marked his third career multi-touchdown game in the regular season.

4. Travis Kelce is still really, really good

Kelce leads all NFL tight ends with 772 yards after the catch over the past two seasons. He ranks third in receiving yards during with 1,278.

He's currently on pace for more than 1,100 yards receiving this season, which would surpass his career high set last season with 862 yards.

5. Simple: protect to win

In his career, Chiefs quarterback Alex Smith is 46-18-1 in games in which he doesn't throw an interception.

He's also currently on pace for more than 4,100 passing yards this season, which would absolutely shatter his current career best of 3,313 yards set back in 2013.

6. Thou shall not giveth, but thou shall taketh away

The Steelers are tied for the NFL lead with a plus-6 takeaway differential (9 takeaways, 3 giveaways) through Week 6 of 2015.

7. Chiefs first-round pick making a name for himself

Cornerback Marcus Peters is currently tied for fourth in the NFL with 3 interceptions this season, including his impressive display last week against the Minnesota Vikings.

8. Finishing drives hasn't been problem for Steelers

The Steelers lead the NFL through Week 6 by converting 75 percent of their red zone trips into touchdowns (12 of 16).

LAST TIME THEY MET

9. Steelers can bring the heat

The Steelers defense ranks tied for sixth in the NFL with 17.0 sacks in 2015.

Only Russell Wilson (26) of the Seattle Seahawks has been sacked more times this season than Alex Smith (23).

10. Historic win possible against fitting foe

With a win on Sunday, Chiefs coach Andy Reid would pick up win No. 162 of his career, which would move him to No. 18 on the all-time list, passing former Steelers head coach Bill Cowher.
