The 2020 Baltimore Ravens clearly have a more balanced roster than the 2000 Ravens. The 2000 Ravens have a historically good defense and some pieces on the offense that make it work. This would be a very compelling battle and that shows you how good the 2000 Ravens defense really was.
The biggest problem the 2020 Ravens would have is how gap sound the 2000 defense would be. Running up the middle would be a very difficult proposition against Sam Adams and Tony Siragusa. Rob Burnett and Michael McCrary were great at setting the edge. The speed the 2000 Ravens had at their three linebacker positions was amazing.
