I have a weird feeling that UNC plays well tonight for some reason. The intensity variable should be a non-factor. This is their Super Bowl. If they don't play hard tonight, they should forfeit the remaining games.
There were many seasons where Duke had pretty significant size disadvantages against UNC and a lot of those games came down to the wire. I don't recall the size disparity ever being as big as it will be tonight, but there's a path for small teams to stay in the game. Of course, Hubert Davis isn't Coach K, lol.
But I think UNC plays well tonight. Might not be enough for a win, but they'll be in it.
