​PITTSFORD — Dorian Williams or Kaleb Elarms-Orr? Experience or upside?That’s what the assumed competition was supposed to be as the Buffalo Bills searched for an inside linebacker to pair with Terrel Bernard. Elarms-Orr was getting most of the first-team reps early in camp as Williams slowly worked his way back from bilateral knee fractures, while Williams has been with the first team over the last three practices.Bills defensive coordinator Jim Leonhard didn’t shy away from the idea of a competition Thursday, but he also acknowledged there won’t necessarily be a winner and a loser.The Bills have rotated the three linebackers liberally throughout 11-on-11 sessions, as Bernard is still ramping up from offseason ankle surgery. But the Bills have also shown different looks with their linebackers.Buffalo has played 3-4, nickel, dime and even a five-man front with one linebacker as they gradually dig deeper into Leonhard’s playbook. And it’s nothing new for Williams, who frequently played on the line of scrimmage on third downs for Sean McDermott over his first three seasons.“There’s going to be roles for all of them,” Leonhard said. “They can all play and they have a little bit different skill sets. It’s exciting to see them go more. … They want to go. They don’t want to leave the field. They want to get as many reps as possible.”Bernard acknowledged the Bills are still in the infancy of Leonhard’s playbook. We haven’t seen any exotic blitzes or players lined up in places offenses don’t expect — and likely won’t — during training camp.That includes outside linebacker Michael Hoecht, who is expected to be used in different packages, but has played sparingly in 11-on-11 sessions while recovering from Achilles surgery.But Leonhard has drawn strong reviews from players in his ability to explain what the Bills are doing and why. Part of that is his ability as a coach, but also has 10 years of NFL experience as a player.“Him having that background as a former player and understanding what we’re going through and the challenges of what we do, I think that’s a big help with our mindset,” Bernard said. “And then obviously he’s been coaching a long time now, so there’s that aspect of it too.”Leonhard, meanwhile, praised the communication skills of his top three linebackers. In McDermott’s defense, Bernard frequently directed traffic, but the safeties were also a big part of the communication.For Leonhard’s defense, the linebackers do most of the communication. Bernard struggled at times with that last year as former coaching staff had a large menu of checks based on the offense and calls were sometimes delayed into the huddle.The new coaching staff love Bernard’s ability to see the field and communicate what he sees to coaches after the play. He’s already earned enough respect to speak his mind freely and chats with Leonhard 15 minutes per day before practice.“He’s been in this position long e
