Yeah and that's why that list is bunk. Also shows how important QB play is since the Falcons will likely be at least a .500 record.
Seriously though, by most standards and reports, Willy Mo is considered one of the best safeties in the NFL, and he's average according to their system.
We will see if they are 500. Your division is brutal IMO and hte NFC in general is tough. You have a great QB and a great WR and another really good one. I just don't really see much proven talent otherwise on your roster.
