Kyle's averaged 4.3 sacks per season over his career (41.5 in 156 games), so I'm not sure why people think he's a sack master. His best year was 10.5 in 2013. After that, the best was 5.5 in 2010:

He remains a solid contributor in my opinion, with his Denver game being his best performance in several years. He was a difference maker in that game, especially on the final toss by Siemian that went incomplete because Kyle blew up the pocket.
Of the multitude of issues this team faces, KW is near the bottom of the list IMO...
