After Preston Brown left in free agency, the Buffalo Bills had a gaping hole at the middle linebacker spot. The Bills didn't do anything in free agency to fill that hole and relied heavily on using their plentiful draft picks to fix that.
Tremaine Edmunds was a projected top-ten pick and luckily for the Bills he fell into the middle of the first round where they could make a move and trade up to get their guy to quarterback the defense for years to come.
Over the first couple of weeks of OTAs, Edmunds and defensive coordinator Leslie Frazier were able to get familiar with each other.
