Sounds suspiciously like a linebacker. Unfortunately he's been our starting safety for 7 years.
It is similar, it is basically a rover. Like I said, he is good when playing closer to the line. He did this very well in 09 (made the pro bowl), and in 2011 he led all of the NFL Safeties in sacks. He had 7.5 for the 2011 season, along with 2 forced fumbles. In 2010, the Saints defense was ranked in the top 5, believe it or not. He had 3 sacks and 6 forced fumbles that season.
I will not dispute the fact that he is awful in coverage, but he does do some things well, and Ryan's scheme works towards his strengths.
If he won't restructure, then I'd be fine with a cut.
