The Detroit Lions will use a committee-style leadership structure for the remainder of the season after dismissing president/general manager Matt Millen, but smartly they have made no long-term decisions about his future replacement(s).
For now, Assistant General Manager Martin Mayhew has been promoted to general manager and will report directly to owner William Clay Ford. Meanwhile, Executive Vice President Tom Lewand will handle all business matters and also report directly to Ford.
According to a news release, the team "will undergo a thorough and comprehensive evaluation of our entire football operation" after the season. That statement leaves open all possibilities and, if nothing else, buys the Lions enough time to give the situation plenty of thought.
