What To Like
In the 3-4 defensive schemes having a long frame athletic player is a must. Jarrett Grace is that player as he's got good physical size to line up as an edge rusher or drop back into coverage in midfield. Long and rangy, Grace has played at one of the top prep programs in the Midwest and excelled. There is no reason to feel he won't do the same at Notre Dame.
What May Concern You
In high school Grace plays in a lot of 5 man fronts and is in the middle of the action as a linebacker. In college he'll have to spend more time up on the line coming off the edge and will have to adjust his game to play against bigger offensive linemen. With work in a college weight room Grace should be able to make this adjustment.
When Brian Kelly talks about RKG players he's talking about Jarrett Grace. On and off the field Kelly and his staff will know what to expect out of Grace. While he's still got work that needs to be done on the field, his best football looks to be ahead of him.
