Crennell is an interesting one because he's had ties to Parcells since the 80's, and honestly really didn't do that bad of a job in Cleveland considering that organization is a complete failure from top to bottom and nobody will ever win there. We may need a defensive coordinator at the end of the season, Paul P. isn't going to survive long with the worst fourth quarter defense i've ever seen. At least Crennell has had success as a coordinator, as opposed to Weis who had Brady and then went to one of the greatest programs in the history of college sports and made them even worse.
