New kickoff rule made Kene less valuable. Kene is amazing in the open field in free-flowing situations when he could just hit his top speed, and struggled in condensed situations where he instead needed to break tackles and/or wait for other people to block for him (hence why he never quite took off in standard drop-back roles). The new kickoff has things far more condensed and static than it used to be, where the kickoff is most similar to a wide zone run play that has him waiting for numerous blocks rather than just finding one seam at his top speed. Doesn't suit his skill set as much, unfortunately.
