Mike Tomlin is digging in to find a replacement for defensive coordinator Keith Butler, who announced his retirement Saturday.
But who that replacement will be could help shape what his team looks like moving forward.
Senior defensive assistant/secondary coach Teryl Austin is the leading candidate to replace Butler, who had been the team's defensive coordinator since 2015 and been with the team since 2003.
But Tomlin also has requested permission to speak to Giants defensive coordinator Patrick Graham, as well. Graham is still currently under contract with the Giants despite the team firing head coach Joe Judge last week.
