It's a brutal blow for a player whom we thought could break out in 2013. It's also devastating for the Saints, who badly need the pass-rush help.
Butler was one of the four players competing to be Ryan's "Jack" linebacker in 2013. That's essentially the glamour position in a 3-4 defense, the position that gets the most opportunities to record big sack totals. We thought Butler was the favorite for the role because of the explosive skills he showed when given the chance with the Cowboys.
