I, too, think the 49'er's are a bit over rated. That's not to say they aren't good, but just as was the case with the Packer's last season, the record makes them look better than they really were. The addition of Moss doesn't change anything for me. If he was capable of making a substantial impact, he wouldn't have been out of work to begin with. Their defense is legit, which is why I say they are good. However, their offense doesn't scare me and I think teams such as the Saints, Patriots, Giants, Steeler's, Ravens, Packers, Texans, and possibly even the Falcons, Panthers, Bears, and MAYBE the Lions are better. I expect the Seahawks to push them hard this season as well, but that depends on them getting QB play at least to the level of Alex Smith.
As I said, I think they are good, not great. To be fair, though, they should have won the NFC Championship game. I'm still not a believer in Alex Smith, Crabtree, Moss, and approaching the same for Gore, at this point. The guy has been ran into the ground and if they stray from the run first approach even a little, I think it will hurt them overall. Manningham is an OK 3rd receiver, but nothing amazing. As others have said, 10 wins sounds reasonable, especially considering the borderline pathetic division they are in. But I do not expect them to be competing for a Super Bowl. They were over achievers last season, and I expect them to come back down to earth this season. At this point, I stand by my opinion, even if they beat the Packer's week one. All I'm worried about is the Packer's getting hot at the right time and making the playoffs. Honestly, I'm not so sure I care if they even have home field advantage throughout. Going to a dome might very well benefit the Packer's offense in several ways, although perhaps I'm very wrong.
