Ken Walker at 17, a 23 implied team total for the Kansas City Chiefs. No left tackle Josh Simmons...Kenneth Walker being used in the screen game, being used as as a receiver. If that is true, this is going to be a great spot
STACKED’s take
Ranked 17th; receiving role opportunity with left tackle out
Kenneth Walker is ranked at 17 in Week 1 FLEX rankings against Denver with a 23 implied team total for Kansas City. Offseason talk suggests Walker will be used in the screen game and as a receiver; with Kansas City's left tackle Josh Simmons out and the Chiefs unlikely to run the ball down Denver's throat, Walker's receiving role could be a great spot to showcase his versatility. A strong Chiefs offensive performance where Walker looks good could result in ranking Chiefs players a tier or two higher for the rest of the season. Additionally, Walker's rushing volume is projected to replace some of Rashee Rice's short-area targets in the Chiefs' offense; if Walker does not produce on the ground, Rice could see increased target volume.
