The analysis is simpler than what is outlined. The Bills have failed to identify a difference maker on the D line. Oliver has been a B+ player who sometimes flashes “A.” Jones with K.C. is an “A” who flashes “A+.”
Also,, Tre White’s injuries severely degraded his playing ability. So the third level of the Bills D lacked a playmaker.
Finally, coaching has been huge. K.C. has out coached Buffalo in the big moments.
