Here is a quick look at the 6-6, 225-pound defender.
WHAT TO LIKE
It's easy to see why Notre Dame fell in love with Mattingly as he fits the mold the Irish have recruited since Brian Kelly took over the program, possessing length and athletic ability. On film I've see Mattingly play on both sides of the ball and make plays with great intensity. He will be the perfect running mate for Jaylon Smith in the coming years.
WHAT MAY CONCERN YOU
We don't feel distance from home will play a factor when Mattingly revisits his decision over the next seven months prior to National Signing Day. One potential area of concern is the amount of weight Mattingly can add to his frame. However, I've seen Notre Dame strength and conditioning coach Paul Longo work his craft, so it shouldn't be a chief concern for Irish fans. The biggest adjustment for Mattingly will come when he arrives on campus and is challenged on and off the field.
Mattingly is a player who can play multiple positions when he reaches Notre Dame. Right now all signs point to him lining up on the edge as an outside linebacker. However, he also could put his hand down and line up as a defensive end in the Irish 3-4 scheme. If needed, I could also see a move over to tight end much like the move made by Troy Niklas.
