I'm not down on Cyrus and I like the pick but I did want to comment on the 3 videos provided in the link. I'm not so sure each one of those aren't penalties in the NFL.
In the first video Cyrus shows excellent burst and pushes the defensive player back nicely - but after that initial hit the player attempts to get around him and is being held as you see the left shoulder pad fly up in the air, he then continues to hold the remainder of the play. This defensive player was not going to make the tackle and Cyrus better learn to know when to let go so that holding isn't called so far away from the play.
In the second video it's quite obvious he slaps the defensive player in the back to push him down. That's a penalty all day. I'm not sure if this is a signature move of his but if he can get in front of the defender and slap him on the side of his upper body ala Reggie White, it would be one awesome move. I've always wondered why more people don't use the "Reggie move" and I wasn't even thinking offensive lineman using it. Kind of like why don't people learn they sky hook like Kareem mastered?
The 3rd video is similar to what I was saying in the first but Cyrus IMO does a much better job of engaging and driving back (almost 5 yards), but at the end he should let go, especially when the job is done.
