I'm guessing you start 2 rb 2 wr 1 flex
If so, I wouldn't start Allen nor Karlos over Murray, Lynch/Rawls, Stewart.
I wouldn't start James Jones over any of WRs, he is way too inconsistent.
But I can see KC starting for you week 16 vs Atl if the Panthers D doesn't get the job done and can't handle Julio & Freeman in week 14... You might even start them next week (KC vs Oak, Car vs NO)
#1 KC DST, #2 Allen, #3 Williams and #4 James Jones
