Truly, he's had 3 sacks in 3 games... which is a pro bowl level of production in the regular season (16 sacks in 16 games).
Gregory has been getting his sacks in limited playing time because so many players who will not be on the team are getting play time. Had Randy been playing the whole game, you'd think he'd have a few more.
Not to mention that I have seen two defensive penalties that have wiped out what would have been two more sacks for Gregory. Add in a couple of holding penalties on the OL trying to stop him and another sack or two likely would have come had they not held.
So, in playing part time in 3 pre season games, Gregory very easily could have been sitting there with 5 or 6 sacks, and that isn't much of a stretch.
Of course, he is playing in preseason games so he likely played some against some back ups, but even then it is a very impressive feat. And I do know some of his sacks have come against starting players too.
If you step back and take a global view of Randy's preseason, you can't help but be extremely impressed with him and what he's been able to do. He has drawn raves from Garrett and Marinelli, neither of who hand out praise very often. Even the media, who tend to take a more cynical view of things, have been raving about Gregory's play in games as well as in practices.
Had he been the Cowboys first round pick everyone would be thrilled with him. Getting him at 60 overall and watching him tear it up all camp long has people beyond thrilled... except for Giants, Eagles, and Commanders fans, of course.
