There is always a darkhorse that does rise up through out the year, I don't know who that is this year.
There are some interesting teams out there to watch. Villanova took a Syracuse team to the wire that was ranked higher than ISU in a majority of preseason polls this year. Was that game a fluke? Can SDSU hang around long enough for Sumner to get back to healthy and have a chance at the postseason? There are east coast teams who recieved multiple transfers during the offseason, as Braden Hanson proved a few years ago, the right fit can win you some games.
My point was, we have watched one week. There will be teams who improve dramatically from week 1 to week 2. I watched a special with Mack Brown and Nick Saban and they talked about how you just try and survive week 1 to see what you have in game situations and make adjustments there after. There will be a lot of teams making adjustments after this past weekend so I am not ready to write off every other team except two after a week of play.
