That is an incredibly hot take there.
Kareem's ineffective streak was absolutely a byproduct of the Chiefs offense sputtering.
Let's do some analysis of the aforementioned weeks:
Week 4: 21 Carries for 101 yards 4 catches for 20 yards. Argument doesn't need to be made. Over 5 YPC and a good ppr game.
Week 5: 29 Carries for 107 Yards 3 catches for 9 yards. Once again, argument doesn't need to be made.
Week 6: 9 Carries for 21 yards 5 catches for 89 Yards. Bottled up on the ground, albeit in limited carries. So I'll give you that one. Still made his line respectable in the pass game.
Week 7: 18 Carries for 87 yards 4 Catches for 30 yards. Almost 5 YPC. Effective line once again.
Week 8: 22 Carries for 46 Yards 3 catches for 22 yards. Absolutely brutal line. I remember watching this game, and Denver had him bottled up. I'll give you this one.
Week 9: 9 Carries for 37 Yards 4 catches for 24 yards. Over 4 YPC but again, limited touches. This was the beginning of Reid's offense starting to sputter. Won't chalk this one up to the Cowboys 'figuring' him out.
Week 11: 18 Carries for 73 Yards 3 Catches for 4 Yards. Again, over 4 YPC.
Week 12: 11 Carries for 17 Yards 1 Catch for 9 Yards. Bottled up again. Watched this one as well. Whole Chiefs offense was a dud this game if I remember correctly.
Week 13: 9 Carries for 40 yards 3 catches for 23 yards. Effective, but limited touches. I chalk this one up to Reid.
Followed by three weeks of scorching the earth and winning a lot of people championships.
By my count, I had two weeks where he was absolutely 'figured out'. Other than that, he was effective with what he was given. Now, I am not ignorant enough to think Ware will make no dent in Kareem's workload. I see him being a COP back that could, like mentioned above, probably vulture some receiving TDs away from Hunt. However, to think that Spencer Ware is going to supplant Hunt completely is, in my opinion, crazy.
