After reading some stuff about Ngakoue I don't think he is a guy that we would seriously entertain trading for. The Hawks have certain measurements that they rarely overlook, even for good players, and he falls short on a few of those measurements. Combine that with the fact that although he certainly is a very good pass-rusher for his age he hasn't produced at an elite level yet (8, 12.5, 9.5, 8 sacks in his 4 years). When you look at things like pass-rush win rate and things like that he isn't a top 10 guy. He isn't double teamed alot, but played on a DL where guys were double teamed a lot. In other words, he was given a lot of opportunities to win a one-on-one battle and he just didn't produce at an elite level. That's not to say he won't. He is only 24 and has a lot of room to grow, but if he doesn't check off on the Hawks key measurable and isn't winning at a consistent rate I would think that he's not really on the Hawks radar, but who knows he definitely is intriguing and he is elite when you look at his sack by age ranking in NFL history, 37.5 career stats and he isn't even 25 yet!!! That is major production, but not Donald/Watt/Von Miller/Kalil Mack type of production. It is slightly better than Frank Clark who did check off on all of the Hawks measurables, but they still weren't willing to pay him over 20 mil/year so It seems far fetched they would sign Ngakoue for more than they would have given Clark.
On another note- I plug this blog a lot but it is really good- this is where I got some of the information about Ngakoue's measurables... If you don't frequent this website come draft season you really are missing out!!!!
