The Giants Super Bowl win was after the 2007 season, but the Super Bowl itself was 2008.
Anyway, great response. How are you ever going to get better if you aren't judging yourself against your competition? It isn't just the NFL that does that. Any well run business is very aware of their competition.
However, I guess you could just continue to operate the same way and hope something changes. I guess you're happy and think this is just a string of bad luck, but the bottom line is that this team isn't good enough, hasn't been good enough and hasn't been as well run as the rest of the upper echelon teams in the league.
