Then Von Miller showed up.
A scheme change in Denver also marginalized the 32-year-old Haggan, who landed in St. Louis and could start for the Rams at strong-side linebacker. James Laurinaitis returns as the starter in the middle, with Jo-Lonn Dunbar penciled in as the starter on the weak side.
Linebacker was one position of great need for St. Louis that went largely unaddressed in the draft. The team used a seventh-round choice for Hawaii's Aaron Brown.
Haggan provides veteran depth, a short-term starting candidate and, potentially, veteran leadership.
The Scouts Inc. report for Haggan heading into last season read, "Haggan is much more effective coming forward than he is when dropping into space and may struggle in Denver's new defensive scheme. He shows good acceleration upfield as a pass-rusher and flashes a decent burst to close on the pocket. He needs work on his hand use as he tries to control and shed blockers. He can be inconsistent reading blocking schemes and locating the level of the ball."
