The Jaguars reached a six-year agreement with Buffalo Bills middle linebacker Paul Posluszny, according to a source.
Posluszny labored with the decision, a source said, because he wanted to stay with the Bills, but he agreed with the Jaguars because of the change to be in a 4-3 defense. The Bills have switched to a 3-4.
Posluszny will be the middle linebacker in Jaguars 4-3.
