FLOWERY BRANCH — Losing linebacker Sean Weatherspoon to a season-ending injury has caused a ripple effect throughout Atlanta's defense. Weatherspoon, a first-round draft pick in 2009, would've started on the inside and run the huddle, but his torn Achilles tendon means that Paul Worrilow and Joplo Bartu now hold starting jobs at both inside spots as the Falcons transition to more 3-4 fronts. "Yeah, we had to do all of the (offseason training activities) without Sean," Worrilow said Wednesday on the second day of mini-camp.
