However, McKinney wasn’t the only member of Green Bay’s defense to succeed under Hafley. Before suffering an ankle injury late in the season, inside linebacker Quay Walker had been playing some of the best football of his career.

If McKinney's words are true, then the banter is just another chapter in the Packers and Detroit Lions rivalry. Yet, when both teams face off next year, it is easy to assume tensions may flare up once again.
