Edda showed well. He appears to be a good draft pick despite the year of rust.
Physically:
He displayed the fast vertical speed that his 40 time suggested, and it was great to see that translate into playing speed. His first step isn't really explosive, but it isn't bad either, but it's his top gear that is most impressive. Laterally he is quicker than average but not exceptional. Size-wise he fits the mold Ireland wants, but Edds biggest problem is that he needs more functional strength. Fortunately, strength can be improved. He gets moved at the point of attack and had a couple of arm tackles that were run through. All in all, an exciting physical package.
Instincts:
He already posseses good instincts and fast mental reaction. He was a bit inconsistent, but that's common for young players. He reads the play, anticipates how it unfolds, and gets where he needs to be very well. I was surprised how well he read the game at ILB. His strength was supposed to be covering TE's and he did not disappoint. I think he is by far our best coverage LB in a long time. The thing that impressed me mostthough, was they way he married his reading and speed to become a very rangy LB and always stay in the play. If he builds on that he can become an impact starter down the road once he builds his functional strength.
All in all he has a lot of potential. I don't know if calling him a starter/backup really has much value, because he is definitely a situational cover LB right now. He showed the read and range to become a good LB, but his strength progression will determine how quickly he forces his way not the base package. For now he isn't strong enough to claim a spot in the base package. But he is always around the ball, so if he starts forcing turnovers he will demand more snaps ... and IMHO he has the ability.
Crowder never made impactful plays and always relied on superior athletic ability to bail out his slow read and respond skills. Edds isn't Zach Thomas, but he is a lot quicker to diagnose plays than Crowder ever was ... which is encouraging.
