Are the Bills readying for a switch to the 3-4 defense?

Maybe the Bills really are serious about switching to the 3-4 defense.

According to The Buffalo News, the Bills sought permission from the Broncos to speak with Mike Nolan before he eventually left to become the new defensive coordinator of the Miami Dolphins.

New head coach Chan Gailey has stated that he has some candidates in mind for the open defensive coordinator position in Buffalo, but declined to reveal any names.

“We're going to get the best teachers — the best people to help fit into a program,” Gailey said. “We're going to get the best people to come in here and be a part of our organization to help us build a winner.”

The pursuit of Nolan makes it clear that the Bills are genuinely interested in making the switch from the 4-3.

Could Clancy Pendergast be a possibility?

Pendergast employed the 3-4 in Kansas City, though he lasted just one year as the Chiefs defensive coordinator. He also ran the 3-4 briefly in Arizona in 2008. The most interesting aspect of his resume is that he was a defensive assistant under Gailey with the Cowboys, and they crossed paths again in Kansas City last year before before Gailey was dismissed by Todd Haley.

Tim Lewis could be another candidate. The Seahawks’ secondary coach under Jim Mora ran Bill Cowher’s 3-4 defense in Pittsburgh from 2000-03.

While Gailey will handle the offensive duties for the Bills, it seems his main concern in his first few days in Buffalo will be to find the right defensive leader for his new club.
