I don't know how to classify who is "great" per se, but they did play Mahomes - former MVP/SB MVP and All Pro. They held him to 23/37 for 260, 0 TD's, 1 Int. He also picked up 11 yds on 7 rushes. Add to that, IMO, this defense is quite a bit better than the one that played against Mahomes in week 12. Overall, regardless of competition level, I just think the defense has significantly improved as the season has progressed. I wouldn't personally put K Murray in the same QB class as Mahomes (although they do have some similarities), and I know that anything can happen in any given week, but I feel good going into this game against AZ.
