The Saints don't have a player named Jack on their 89-man offseason roster. But if they want to return to the NFC playoffs, they need to find a "Jack" somewhere on their defense.
Confused? Don't be. This Jack talk is all new to New Orleans. It arrived here only a few months ago with defensive coordinator Rob Ryan and the 3-4 defense.
The Jack is the Saints' term for the pass-rushing outside linebacker position in their new defensive scheme. The spot is called different things in different 3-4 systems. Some teams call it "the elephant." Others call it "the star." Ryan calls it "Jack," and it might be the most important name on the roster other than Drew.
