The Saints' quest toward improving upon the worst defense in NFL history hit a potential major road block in the first day of free agency as offensive tackle Jermon Bushrod bolted for the Windy City and the Chicago Bears.

As the protector of Drew Brees's blindside, Bushrod held one of the most important positions on the team. The task of keeping Brees upright is made even more important now that Chase Daniel has left for Kansas City to become the Chiefs starting quarterback.

Throughout the off-season, the burning question among Who Dat Nation has been: Who will be brought in to upgrade the defense? Upon being reinstated after serving his year-long suspension, Sean Payton took the first step in this process by hiring Rob Ryan, who had just gotten booted out of Jerry's World, to replace the disaster that was Steve Spagnuolo. The high profile hiring of the outspoken Ryan, who will remake the defense into a 3-4 alignment, has not come without criticism, as he has had mixed results during previous stops with the Browns, Raiders and Cowboys.

Equipped with a new leader and new scheme, the next piece of the puzzle for the Saints defense is the most anticipated. It is also what keeps me reading mock drafts until all hours of the night. The curiosity gripping the majority of the world was answered yesterday when the white smoke started rising from the chimney of the Sistine Chapel, but mine will continue to linger until April 25th when the Saints make their first round draft selection.
