No. 4 Jaguars player who must shine vs. the Chiefs: Christian Kirk, WR
The Colts made an effort to contain wide receiver Christian Kirk and it kind of worked, as he just caught one pass for nine yards. Without context, it looks like Indy did a great job of stopping the Jaguars' offense but by zeroing in on Kirk, they allowed Zay Jones and Christian Kirk, alongside tight end Evan Engram, to run amuk.
The Chiefs will most likely focus on slowing down Ridley and Jones, who had five receptions for 55 yards with one touchdown. This should leave Kirk with favorable matchups throughout the game. Expect him to exploit them and get his first 100-yards game of the season.
As Engram said before the season, opposing teams will have to pick their poison when defending Jacksonville,
No. 3 Jaguars player who must shine vs. the Chiefs: Anton Harrison, OT
Right tackle Anton Harrison wasn't great in his NFL debut, which was expected from a player who switched sides in the offseason. Then again, he wasn't dreadful. While he gave up one sack and his run blocking left a bit to be desired, he was mostly solid in pass protection, scoring a Pro Football Focus grade of 66.8 in that area.
Harrison, like most first-year players, will go through ups and downs while he gets acclimated to the pros. He'll get a chance to take a step in the right direction against the Chiefs. The Jags seemed to be hesitant to run behind him in the opener and rightfully so. That's something he'll need to work on in the upcoming weeks.
