The New York Giants added two new linebackers this offseason, Alec Ogeltree and Kareem Martin.
Martin is a player of former Arizona Cardinals and current Giants defensive coordinator, James Bettcher. With Bettcher comes a 3-4 scheme, or some sort of hybrid system. With the Giants working with a 4-3 system for years, switching to a 3-4 would be an extreme change, which makes a hybrid system more likely.
This benefits Martin and Ogletree greatly, as both are great at the point of attack and were primary run defenders in their respective defenses. GM Dave Gettleman traded for Ogletree to solidify the middle of the field, a position that former GM Jerry Reese avoided oh so religiously.
