I am just sort of happy that the Cowboys play in the NFC and not the AFC. I think SF stayed about the same, they got worse on the DLine, better at WR, and possibly slightly better at LT, and had a decent draft outside of that. I think NO did okay, but are also about the same. Emmanuel Sanders is nice and another good weapon, but does not change the strengths and weaknesses of the team. GB basically wasted their first round pick and while Tampa and Seattle are teams to worry about, I do not think they are legit contenders.
Meanwhile I think KC got better and they were already the SB champs. I think Baltimore basically just spent a ton of capital removing their only weakness in run defense (4 or 5 draft picks or something like that plus FA). The Colts were a great team with weak pass rush and a bad QB and they improved on both counts. The Texans have a top 4 NFL QB right now along with some nice pieces even if their GM is the Jason Garrett of GMs. Tennessee is taking some nice steps to build around a successful season and then you have both Buffalo and Miami as dark horses to watch out for.
So the one benefit is that the path to the Super Bowl is probably easiest to get through the NFC versus the AFC for the foreseeable future which works to the Cowboys benefit.
