They are not the same type of player physically, but Shaq PRODUCED on the field the same number of tackles for loss (13), 1.5 less sacks, was only 9 total tackles behind Yannick, and had 18 QB hits to Ngakoue's 15 in 320 LESS DEFENSIVE SNAPS. It's not all due to the back end of the defense. Murphy is not the better player, especially when you watch the two having to move around in space. Murphy looks dreadful lumbering around out there. The staff likes him though and he is a decent rotational option. I think you could see Frazier and McDermott's trust grow with Lawson as the season went along which is why he started to get more PT as the season progressed. You can see how they used him in the attachment below. I think they want him back and I believe he will see the field a lot more in 2020 if he is.
