Carrier Dome is no paradise, there's no A/C (amazing considering the sponsor, doh) and it is going to be a warm day in Syracuse. Orange has had more then a few upsets on a historic basis on their home field. So it could be interesting. Still think Clemson wins it but don't be surprised if it's closer than expected. A full house is expected and that's a lot of trapped heat. Sometimes it get's a bit foggy inside. Games in November - no problem, except for the snow!
Spot on regarding what it's like in the Carrier Dome. The Dome will be one of the hottest places, if not the hottest place, Clemson will play this year, especially, if it's warm in Syracuse that day. There are tiny ventilation ports near the top of the concrete that supports the roof, but they don't make much of a difference in cooling the place.
Add to that the fact that SU is used to playing there (a turf field that isn't crowned), has a decent amount of speed, the offense is starting to click with Terrell Hunt under center and is usually solid defensively, and SU could make a game of this. I'm not saying SU will win, but i wouldn't be surprised to see SU hang in there.
