From the tape I watched on Hatcher, he doesn't seem to have a "trademark" move, or whatever you want to call it, but he is very good at using his hands to constantly beat on the blocker's hands & arms to keep them from getting into his body. One move I did notice, if you want to call it that, was that he leans in with his inside shoulder against the blocker's chest, then beats on the blocker's outer arm & shoulder to keep from being held, while he's turning him inside toward the ballcarrier-if that makes sense.
The one thing that really impresses me is his ability to read the play very quickly. I know these are all "highlights", but still, this is a very critical skill for such a young player. This allows him to stay one step ahead of his blockers, so he doesn't get taken wide, or trapped inside, like so many young DEs do. His first step is almost always to the outside, watching the whole time for the run. His quickness allows him to begin each play as a pass rusher, then recover to make the play on the RB. Charles Haley was a master at that, & our Mr. Ware is learning it quickly, as well.
If Hatcher develops like I think & am hoping he will, we are going to be quite loaded at the DE position.
