Saints are willing to look past warning signs with Rob Ryan

"The knock on Ryan in previous stops was that he didn't have very sound principles, and that he didn't always find the right balance between when to blitz and when to cover."

This is the biggest thing you all should be concerned with outside of personnel. Don't worry about his personality... that doesn't seem to be much of an issue.

Ryan seems to try to outsmart everyone, but in doing so over thinks. He doesn't appear to have a good feel of how to game plan. He was able to dial up some nice plays toward the end of the year, so he has the ability, but I don't know how many times I saw our best pass rushers drop back into coverage and rush three down lineman (none of them being particularly good pass rushers). More than one occasion, you could find DeMarcus Ware playing a safety type role after the ball was snapped.

He has a lot of exotic and unsuccessful schemes that will make you want to tear your hair out.
This also worries me. I'm hoping for Grantham. We can't afford another bad or even so-so DC hire.
