It's a position that takes many years to exceed in, so that he has put up some good stats early on, is very promising. And looking away from stats, but focusing on games, I have seen most of them, he was around the QB always on passing downs making pressures, but was a big liability on running plays and that's what has kept him from starting. In his last 5 games recovering form the injury last year, he made 3.5 sacks. You can't ask for more than that. 6 sacks in two years with significant injury and time off the field, is much to write home about. Looking at his tapes, he is a great pass rushing talent, and is consistently making troubles for the tackles. I say he is instantly a much greater danger on the edge than Porter or Haggans.
I can't provide links for everything I post. So you can believe me or not. But the site is called profootballfocus and you have to pay and check for yourself - reason that I can't provide the complete link. I remember looking at the stat and it was obvious how many pressures he made compared to the snaps he got, only Orakpo and him could compare from that class. However, we all know that as 3-4 DE/OLB you get many encounters with the RB's and TE's (instead of tackles as 4-3 DE) and several unblocked situations at the QB, therefore many "free" sacks. 6 sacks as DE (in 43)is 10 as OLB in 34 IMHO. If he stays healthy and plays 3-4, he could put up Orakpo stats.
I haven't seen the preseason games, but I really don't put much into it, if he looked bad or not. He looked very good during regular season on passing downs, so he has shown the ability to rush the passer when it matters.
In my opinion he is one of the best young pass rushing talents in the NFL. Another player we should have signed is Nick Reed. Problem with him (Everette) on the tapes is how he handles the run. He needs to bulk up and learn the technique much better to be able to play on all three downs. Also what makes the case for that's possible is that he makes separation against tackles by moves and leverage and the spin move, rather than his speed. So he can put up some weight and keep his pass rushing ability.
