Is Caldwell an intriguing HC option?

The Detroit Lions are slated to interview Baltimore Ravens offensive coordinator Jim Caldwell on Friday. Caldwell also is expected to speak with the Washington Redskins about their head coach opening on Wednesday. Fans of both teams may wonder whether Caldwell really is an intriguing option, considering how thoroughly terrible the Ravens offense was this season. On the other hand, he turned their offense around during their Super Bowl run last season after taking over the controls late in the regular season.
