Two kids no brane
The Giants didn't win the sb in 2010 or 12...Of course the Giants have a shot at winning the SB if they make the playoffs. They're a team that can stop the run and have talented pass rushers and defensive backs. With Odell on offense they're a very, very dangerous team that just needs a couple of bounces here and there to beat any team. Week to week they are extremely dangerous and would be in the playoffs because Odell has a very good chances of closing the season on a hot streak along with the pass rush which seems to have woken up finally. They basically have the players to win it all with some luck like the 2007, 10, 11 and 12 SB winning teams.
The rest of your post is correct though. I think the beauty of being the Giants is people aren't scared of them, so they may not prepare properly for them or underestimate them.
